  Structure-activity relationships of the cycloalkyl ring of phencyclidine

  摘要：

  In order to investigate the structural requirements for a cycloalkyl moiety in the potent hallucinogen 1-(1-phenylcyclohexyl)piperidine (PCP, 1), a series of structural analogues was synthesized in which the size of the cycloalkyl ring was varied from three carbons to eight carbons. Biological activities of these compounds were assessed in an in vitro assay (phencyclidine binding assay) and an in vivo assay (discriminative stimulus assay). As the cycloalkyl ring size decreased from that of cyclohexane (PCP), PCP-like activity declined in both assays, but as the cycloalkyl ring size became larger than cyclohexane, a sharp decline in PCP-like activity was observed in the in vivo assay, while activity in the in vitro assay was only slightly less than that of PCP. 1-(1-Phenylcyclooctyl)piperidine (8) had potent competitive binding properties in the in vitro binding assay but produced no observable PCP-like effects in the in vivo assay. The importance of the cycloalkyl ring in the structure of PCP was demonstrated by testing benzylpiperidine (2), which had almost no measurable activity in either assay.

  摘要：

  通过可见光辐照CH 2 Cl 2溶液（含母体1-烷基环烷醇，（二乙酰氧基）碘苯（DIB）和I 2）通过光化学方法生成的1-烷基环烷氧基自由基的CCβ断裂反应通过对反应产物的分析进行了研究。1-烷基环烷氧基自由基根据环的大小和烷基取代基的性质而经历开环和C-烷基键裂解之间的竞争。利用1-丙基环庚氧基，1-丙基环辛氧基和1-苯基环辛氧基，还观察到形成了源自环烷环的分子内1，5-氢原子抽象反应的产物。根据与开环相关的环应变的释放，由C-烷基裂解形成的烷基的稳定性以及与环庚氧基和环辛氧基基团的讨论，还就获得分子内氢原子的良好几何形状的可能性来讨论结果抽象。

  A metal-free approach for the oxidative cleavage of carbon–carbon double bonds of olefins to carbonyl compounds was established by using oxidant m-CPBA and non-metallic organocatalyst PhI in toluene/H2O. A broad scope of aromatic olefins was used. All the reactions proceeded smoothly at 35 °C in short reaction time to furnish the respective mono- and double carbonyl compounds selectively in moderate

  cleavage of unfunctionalized secondary (2°) and tertiary alcohols (3°) is essential for valorization of macromolecules and biopolymers. We developed a blue-light-driven iron catalysis for aerobic oxidation of 2° and 3° alcohols to acids via α-C–C bond cleavages at room temperature. The first example of oxygenation of the simple tertiary alcohols was reported. The iron catalyst and blue light play critical

  未官能化的仲醇（2°）和叔醇（3°）的选择性α-CC键断裂对于大分子和生物聚合物的增值至关重要。我们开发了一种蓝光驱动的铁催化剂，用于在室温下通过α-CC键断裂将2°和3°醇有氧氧化为酸。报道了简单叔醇氧化的第一个例子。铁催化剂和蓝光起着至关重要的作用，可以使醇类形成高反应性的O自由基，并随后发生两次α-CC键断裂。

  β-Acetoxy alcohols can be synthesized in good yields with excellent diastereoselectivity from tertiary alcohols through PhI(OAc)2-mediated metal-free β-acetoxylation. Mechanistic studies showed that the β-acetoxylation process might undergo dehydration and sequential highly regioselective and diastereoseletive dioxygenation. Gram scale and diverse useful scaffolds could be prepared via this β-acetoxylation

  The utility of triphosgene and DMAP as mild reagents for chemoselective dehydration of tertiary alcohols is reported. Performed in dichloromethane at room temperature, this reaction is readily tolerated by a broad scope of substrates, yielding alkenes preferentially with the (E)-geometry. While formation of the Hofmann products is generally favored, a dramatic change in alkene selectivity toward the

  an alkoxy radical process for the C–C bond cleavage and functionalization of unstrained tertiary and secondary cyclic alcohols. In the absence of a chlorine atom, the readily available iron catalysts [Fe(OBu-t)3 or Fe(acac)3/t-BuONa] facilitate alkoxy radical formation via the direct ligand-to-metal charge transfer of Fe alkoxide and further enable the ring opening and amination of cyclic alcohols.

  我们报告了一种用于 C-C 键断裂和无应变叔和仲环醇官能化的烷氧基自由基过程。在没有氯原子的情况下，容易获得的铁催化剂 [Fe(OBu- t ) 3或 Fe(acac) 3 / t -BuONa] 通过烷氧基铁的直接配体到金属的电荷转移促进烷氧基自由基的形成，进一步使环状醇的开环和胺化成为可能。在温和的氧化还原中性体系下，可以以高产率获得范围广泛的远程氨基羰基化合物。光驱动的电子转移、烷氧基自由基的形成以及随后通过 β 断裂的 C-C 键断裂是转化的关键。
