1,1,3,3-四甲基二硅氧烷(TMDS)和聚甲基氢硅氧烷(PMHS)与异丙醇钛(IV)结合使用时,提供了两个方便的系统,可将腈还原为相应的伯胺。通过1 H NMR研究了这两个系统的动力学,结果表明,用PMHS进行还原的速度比用TMDS进行还原的速度更快。在存在Br,CC,NO 2的情况下,这两个钛基体系同时还原芳族和脂肪族腈,OH和环丙基环。在环丙基腈的情况下,观察到由于分子间还原性烷基化反应而形成的仲胺。该结果被用于还原二腈,其通过分子内还原性烷基化反应一步一步导致了氮杂环庚烷,哌啶,吡咯烷和氮杂环丁烷衍生物。

Substituted acrylophenones and related mannich bases as possible spermicides and inhibitors of HIV envelope glycoprotein–CD4 interaction
subjected to the Mannich reaction to yield compounds that would incorporate both alpha,beta-unsaturated keto groups and a substituted aminomethyl function with or without another olefinic moiety at position 4. The spermicidal activity of the prepared compounds was evaluated. Several compounds 2d, 4a and 4e were found to possess spermicidal activity at 0.005% concentration, while compounds 2a, 2c, 2f, 3a and

A rapid, convenient conversion of 1,2-dimethylpyrazolium salts (1) to 1-methylpyrazoles (2) is accomplished in piperidine or 3-methylpiperidine at temperatures ≥ 106°. This demethylation represents a particularly useful procedure for the synthesis of 3- and 5-substituted aminopyrazoles, which are not readily obtainable by other methods. The 50:50 mixture of piperidinopyrazole isomers 2b can be obtained
