    α,β-不饱和酮的催化对映选择性过氧化
    摘要:
    尽管手性过氧化物具有作为生物学上有趣的甚至临床上重要的化合物的潜力,但尚未报道催化对映选择性过氧化。手性催化剂不仅可以诱导对映选择性,还可以将完善的环氧化途径转化为过氧化途径,成功开发了第一个有效的催化过氧化。采用容易获得的α、β-不饱和酮和氢过氧化物以及易于获得的金鸡纳生物碱催化剂,这种新反应将为手性过氧化物的不对称合成开辟新的可能性。在不同条件下,还建立了使用相同起始材料、试剂和催化剂的高度对映选择性环氧化反应。

  • Comparative Safety of Filgrastim versus Sargramostim in Patients Receiving Myelosuppressive Chemotherapy
    作者:Gary Milkovich、Ronald J. Moleski、John F. Reitan、David M. Dunning、Gene A. Gibson、Thomas A. Paivanas、Susan Wyant、R. Jake Jacobs
    DOI:10.1592/phco.20.19.1432.34861
    日期:2000.12
    Study Objective. To compare rates of adverse events with filgrastim versus sargramostim when given prophylactically to patients receiving myelosuppressive chemotherapy. Design. Retrospective review with center crossover. Setting. Ten United States outpatient chemotherapy centers. Patients. Four hundred ninety patients treated for lung, breast, lymphatic system, or ovarian tumors. Intervention. Prophylactic use of filgrastim or sargramostim, with dosages at investigator discretion. Measurements and Main Results. The frequency and severity of adverse events and the frequency of switching to the alternative CSF were assessed. There was no difference in infectious fever. Fever unexplained by infection was more common with sargramostim (7% vs 1%, p<0.001), as were fatigue, diarrhea, injection site reactions, other dermatologic disorders, and edema (all p<0.05). Skeletal pain was more frequent with filgrastim (p=0.06). Patients treated with sargramostim switched to the alternative agent more often (p<0.001). Conclusion. Adverse events were less frequent with filgrastim than with sargramostim, suggesting that quality of life and treatment costs also may differ.
    研究目的:比较在接受骨髓抑制化疗的患者中,预防性使用菲尔格司亭与沙格莫司亭的副作用发生率。 设计:回顾性研究,具有中心交叉设计。 设置:美国十个门诊化疗中心。 患者:490名接受肺癌、乳腺癌、淋巴系统或卵巢肿瘤治疗的患者。 干预:在研究者的判断下,预防性使用菲尔格司亭或沙格莫司亭,剂量由研究者自行决定。 测量与主要结果:评估了副作用的发生频率和严重程度,以及转用替代性粒细胞生长因子的频率。感染引起的发热没有差异。与沙格莫司亭相比,不明原因的发热更为常见(7%对1%,p<0.001),疲劳、腹泻、注射部位反应、其他皮肤病和水肿也更常见(均p<0.05)。骨骼疼痛在使用菲尔格司亭的患者中更为频繁(p=0.06)。接受沙格莫司亭治疗的患者更常转用替代药物(p<0.001)。 结论:与沙格莫司亭相比,使用菲尔格司亭的副作用发生率更低,这表明生活质量和治疗费用也可能存在差异。
  • A New Protocol for a Regioselective Aldol Condensation as an Alternative Convenient Synthesis of β-Ketols and α,β-Unsaturated Ketones
    作者:Therapia Kourouli、Panagiotis Kefalas、Nikitas Ragoussis、Valentine Ragoussis
    DOI:10.1021/jo0200872
    日期:2002.6.1
    A general and convenient synthesis of beta-ketols and alpha,beta-alkenones has been achieved by a Knoevenagel condensation of a beta-ketoacid with an aldehyde in aqueous medium. Saponification of a beta-ketoester by an aqueous KOH 10% solution gives the potassium salt of the beta-ketoacid, which is condensed in situ with an aldehyde at pH 7.8-8.0, at 60 degrees C for 5-6 h. The intermediate beta-ketocarboxylate
    通过在水性介质中将β-酮酸与醛进行Knoevenagel缩合,可以实现β-酮醇和α,β-烯酮的常规合成。用10%的KOH水溶液将β-酮酸酯皂化,得到β-酮酸的钾盐,将其与醛在pH值为7.8-8.0的条件下于60摄氏度下原位缩合5-6小时。中间体β-酮羧酸酯在反应介质中平滑脱羧,从而以高收率(75-90%)得到β-酮醇。将反应混合物在pH 1下酸化并在剧烈搅拌下于70°C加热6小时,可直接生成相应的α,β-不饱和酮,收率良好(65-75%)。
