...对叔戊基甲基醚（TAME）在大鼠和一名志愿者体内的生物转化进行了研究，在吸入(12)C-或(13)C标记的TAME后。此外，还研究了叔戊醇[(13)C]在大鼠灌胃后的生物转化。...大鼠（两雄两雌）分别暴露于2000 ppm [(12)C]-或[(13)C]TAME 6小时，并收集48小时的尿液。以(13)C NMR信号的相对强度为依据，将自由态和葡萄糖苷化的2-甲基-2,3-丁二醇以及叔戊醇的葡萄糖苷酸定为主要尿液代谢物。根据(13)C NMR，还表明存在几种次要代谢物，它们被鉴定为叔戊醇、2-羟基-2-甲基丁酸和3-羟基-3-甲基丁酸。一名志愿者通过吸入2升气袋中的27,000 ppm [(13)C]TAME 初始浓度4分钟，并分析了尿液中TAME的代谢物通过(13)C NMR。在大鼠中鉴定的所有TAME代谢物也存在于人类尿液中。为了研究叔戊醇的生物转化，雄性大鼠（n = 3）通过灌胃250 mg/kg [(13)C]-叔戊醇溶解在玉米油中处理，并收集48小时的尿液。尿液样本的(13)C NMR显示了与[(13)C]TAME处理的大鼠尿液中相同的代谢物存在。我们的结果表明，TAME在大鼠和人类体内广泛代谢为叔戊醇，叔戊醇可能进一步氧化为二醇和羧酸。这些反应可能是由细胞色素P450依赖性氧化介导的。

... the biotransformation of tert-Amyl methyl ether (TAME) /was studied/ in rats and one human volunteer after inhalation of (12)C- or (13)C-labeled TAME. In addition, the biotransformation of [(13)C]-tert-amyl alcohol was studied in rats after gavage. ... Rats (two males and two females) were individually exposed to 2000 ppm [(12)C]- or [(13)C]TAME for 6 hr, and urine was collected for 48 hr. Free and glucuronidated 2-methyl-2,3-butanediol and a glucuronide of tert-amyl alcohol were identified ... as major urinary metabolites on the basis of the relative intensities of the (13)C NMR signals. The presence of several minor metabolites was also indicated by (13)C NMR; they were identified as tert-amyl alcohol, 2-hydroxy-2-methylbutyric acid, and 3-hydroxy-3-methylbutyric acid. One human volunteer was exposed to an initial concentration of 27,000 ppm [(13)C]TAME by inhalation for 4 min from a 2 L gas sampling bag, and metabolites of TAME excreted in urine were analyzed by (13)C NMR. All TAME metabolites identified in rats were also present in the human urine samples. To study tert-amyl alcohol biotransformation, male rats (n = 3) were treated with 250 mg/kg [(13)C]-tert-amyl alcohol dissolved in corn oil by gavage, and urine was collected for 48 hr. (13)C NMR of the urine samples showed the presence of metabolites identical to those in the urine of [(13)C]TAME-treated rats. Our results suggest that TAME is extensively metabolized by rats and humans to tert-amyl alcohol which may be further oxidized to diols and carboxylic acids. These reactions are likely mediated by cytochrome P450-dependent oxidations.

该研究的目的是使用基于生理学的药代动力学（PBPK）模型来描述叔戊基甲基醚（TAME）及其主要代谢物叔戊醇（TAA）在雄性Fischer-344大鼠体内的处置情况。TAME和TAA的模型室是流量受限的。TAME的生理模型有6个室：肺、肝、快速灌注组织、慢速灌注组织、脂肪和肾脏。TAA模型有3个室：肺、肝和总体水。这两个模型通过TAME在肝脏中代谢为TAA而相互连接。模型模拟与从雄性Fischer-344大鼠在6小时吸入2500、500或100 ppm TAME暴露期间和之后采集的TAME和TAA血液浓度数据进行了比较。当包括两个可饱和的TAME氧化途径时，PBPK模型预测了TAME的药代动力学。包括TAA氧化和葡萄糖醛酸苷结合途径的TAA模型，在暴露后较晚时间点的实验数据收集时预测偏低。为了解释这一时期的生物过程，提出了三种假设：TAA的非特异性结合、TAA的扩散限制传输和TAA葡萄糖醛酸苷的肠肝循环。这些假设通过三种不同的模型结构进行了测试。视觉检查和最大似然技术的统计分析表明，包含TAA非特异性结合的模型与数据的拟合效果最好。

... The objective of this study was to use a physiologically-based pharmacokinetic (PBPK) model to describe the disposition of tert-amyl methyl ether (TAME) and its major metabolite, tert-amyl alcohol (TAA), in male Fischer-344 rats. The model compartments for TAME and TAA were flow-limited. The TAME physiological model had 6 compartments: lung, liver, rapidly perfused tissues, slowly perfused tissues, fat, and kidney. The TAA model had 3 compartments: lung, liver, and total-body water. The 2 models were linked through metabolism of TAME to TAA in the liver. Model simulations were compared with data on blood concentrations of TAME and TAA taken from male Fischer-344 rats during and after a 6-hour inhalation exposure to 2500, 500, or 100 ppm TAME. The PBPK model predicted TAME pharmacokinetics when 2 saturable pathways for TAME oxidation were included. The TAA model, which included pathways for oxidation and glucuronide conjugation of TAA, underpredicted the experimental data collected at later times postexposure. To account for biological processes occurring during this time, three hypotheses were developed: nonspecific binding of TAA, diffusion-limited transport of TAA, and enterohepatic circulation of TAA glucuronide. These hypotheses were tested using three different model structures. Visual inspection and statistical evaluation involving maximum likelihood techniques indicated that the model incorporating nonspecific binding of TAA provided the best fit to the data. ...

2-甲基-2-丁醇（4.1 mmol/kg）在大鼠（雄性，Sprague-Dawley，体重160至300克）腹膜内给药戊醇后8分钟引起了行为性中毒。中毒程度按照0到4的等级评分，其中3分代表“几乎不恢复或没有恢复翻转反射，重度镇静，无自发运动活动，肌肉软弱无力，骨盆和腹部不抬起”，2分代表“重度镇静，明显的运动协调障碍和迟缓动作，四肢远离身体伸展”。仅给予2-甲基-2-丁醇后，中毒评分大约为2.9。预先给予咪唑苯二氮䓬Ro15-4513（在给予酒精前5分钟）部分逆转了2-甲基-2-丁醇的中毒作用，评分降低到大约1.8。Ro15-4513在乙醇处理后比戊醇处理后更能有效减少中毒程度。

2-Methyl-2-butanol (4.1 mmol/kg) induced a behavioral intoxication in rats (male, Sprague-Dawley, 160 to 300 g) at 8 min after the intraperitoneal administration of the pentanol. The intoxication was scored on a scale of 0 to 4, where 3 = 'very little or no recovery of righting reflex, heavy sedation, no spontaneous locomotor activity, flaccid muscles, absence of pelvic and abdominal elevation' and 2 = 'heavy sedation, pronounced motor coordination and sluggish movement, limbs extended away from the body'. After 2-methyl-2-butanol alone the intoxication was scored as approximately 2.9. The prior administration of the imidazobenzodiazepine Ro15-4513 (5 min before the alcohol) partially reversed the intoxication by 2-methyl-2-butanol and the score decreased to approximately 1.8. The Ro15-4513 was more effective at reducing the intoxication after treatment with ethanol than after treatment with the pentanol.

制备方法与用途

叔戊醇

简介 叔戊醇，系统名为2-甲基-2-丁醇，是一种无色透明的液体。它微溶于水，并能与水形成共沸混合物，共沸点为87.4℃。叔戊醇能够与乙醇、乙醚、苯、氯仿及甘油等物质混溶。作为化工原料，叔戊醇广泛应用于合成香料、医药和彩色胶片等行业。

七十年代中叶，日本通过以叔戊醇为原料合成中间体频那酮取得了成功，推动了一系列高附加值产品的开发，使叔戊醇的深度加工达到了新的高度。

化学性质

无色易燃液体，燃烧时散发类似樟脑的独特气味。它能溶解于8倍量的水中，并可与乙醇、乙醚、苯、氯仿和甘油及各类油类混溶。水溶液呈中性。

用途

用作合成香料和农药原料的同时，也是优质的溶剂。 主要用于生产新型农药如粉锈宁、频那酮、三唑酮、三唑醇以及种子保护剂；并用于合成茚烷麝香及作为彩色胶片的成色剂。此外，甲基丁炔醇——叔戊醇的中间产物，亦是有效的医药中间体和萜烯类香料中间体，并应用于酸蚀抑止剂、粘度稳定剂、减粘剂以及镀镍、镀铜上光剂与氯化烃稳定剂等。

生产方法 （1）以丙酮与乙炔为原料，经炔化加氢而得。

将乙炔溶解在液氨中，并与丙酮和催化剂混合后送入炔化反应器。反应液经过闪蒸分离未反应的乙炔及氨，随后加热除去未反应的丙酮，得到甲基丁炔醇进入加氢反应器，在此生成叔戊醇并经脱水精制而成产品。

（2）由异戊烯加水而成。 （3）通过将戊烷进行氯化和水解后分馏而得。原料戊烷先经过无水氯化氢处理去水，然后蒸发并与氯气混合进入反应器，在250-300℃温度下发生反应生成物，经四个精馏塔分离得到氯戊烷。在水解器中使用油酸钠作为催化剂和氢氧化钠溶液将氯戊烷水解为粗戊醇，通过与水分离、蒸馏可获得含有伯醇（59%）、仲醇（36%）及叔醇（5%）的混合物。

采用丙酮与乙炔为原料的方法可产出纯度高达99%的产品。原料消耗定额：每吨产品需要1040公斤丙酮、1500公斤电石、650立方米氢气（99.5%）、液氨135公斤以及碳酸钾340公斤。

  Enthalpies of hydration of alkenes. 4. Formation of acyclic tert-alcohols

  摘要：

  The enthalpies of hydration of a series of acyclic alkenes that lead to tert-alcohols were determined. Several pairs of alkenes that give the same alcohol were studied and gave the differences in enthalpy of formation of the alkenes. A consistent difference in DELTA-H(f) of 1.84 kcal/mol was found between di- and trisubstituted alkenes. It was related to the difference in DELTA-H(f) for pairs of exocyclic and endocyclic alkenes. The enthalpies of formation of the alcohols were obtained and were related to data for primary and secondary alcohols.

  A New Indirect Application of Aggregative Activation: Synthesis of Esters by Cobalt-Catalyzed Carbonylation of Aryl, Heterocyclic, and Vinyl Halides under Atmospheric Pressure

  摘要：

  Sun lamp illuminated alkoxycarbonylation of aryl, heteroaryl, and vinyl halides was performed under atmospheric pressure of CO in the presence of a cobalt catalyst in situ generated from Co(OAc)(2). Illumination through a Pyrex flask was sufficient to catalyze the reaction. This process avoids the use of Co-2(CO)(8) and excess CH3I, which were required in the earlier procedure. A S-RN(1) mechanism is proposed.

  Herein a new synthetic route to 1,2-amino alcohols is presented by using C-H amidation of sp(3) methyl C-H bonds as a key step. Readily available alcohols were employed as starting materials after converting them to removable ketoxime chelating groups. Iridium catalysts were found to be effective for the C-H amidation, and LAH reduction was then used to furnish beta-amino alcohol products.

  在本文中，通过使用sp（3）甲基CH键的CH酰胺化作为关键步骤，提出了一种合成1,2-氨基醇的新途径。在将现成的醇转化为可除去的酮肟螯合基团之后，将现成的醇用作起始原料。发现铱催化剂对于CH的酰胺化是有效的，然后将LAH还原用于提供β-氨基醇产物。

  An effective method for alkoxycarbonylation of (hetero)aryl bromides is developed in the presence of in situ-generated phosphinite ligands tBu2POR (R = nBu, nPr, Et or Me). For this purpose commercially available tBu2PCl was used as the pre-ligand in the presence of different alcohols. For the first time cross coupling reactions with two alcohols – one generating the ligand, the other used as substrate

  在原位生成的次膦酸酯配体t Bu 2 POR（R = n Bu，n Pr，Et或Me）存在下，开发了一种用于（杂）芳基溴的烷氧羰基化的有效方法。为此目的，在不同醇存在下，将可商购的t Bu 2 PC1用作预配体。首次开发了与两种醇的交叉偶联反应-一种生成配体，另一种用作底物。通过这种方法，可以以更有效的方式进行配体优化，并且可以以良好的产率和选择性获得所需的产物。

  catalyst-controlled intramolecular unactivated C(sp3)-H amination and oxygenation of carbamates merging visible-light photocatalysis and earth-abundant transition metal catalysis have been reported. Useful amino alcohol and diol derivatives could be selectively obtained from readily available tertiary alcohol derivatives. The possible mechanisms have been proposed via a 1,5-HAT process followed by Lewis acid-controlled
