    某些环烷甲醛在惰性溶剂中的光化学
    摘要:
    环烷烃醛系列的前四个成员在惰性溶剂中的光化学性质为λca 。已经研究了300 nm。环丙烷甲醛的光化学与其他环烷甲醛的光化学不同。所有醛均显示两个主要过程,即T 1过程的α裂解和S 1和T 1都进行的分子间氢提取醛的状态。然后,通过环烷基从甲酰基中提取氢,生成环烷烃和CO。与环丙烷甲醛一起,生成的α-羟基环丙基甲基基团重排,生成3-甲酰基丙基和(Z)-丁-1-烯氧基基团。由于环丙基-羰基键的共轭稳定作用,伴随形成的环丙基羰基基团不会脱羰基。出于同样的原因,环丙烷甲醛仅产生很少的α裂解。与其他三个醛形成的环烷羰基基团很容易脱羰基生成环烷基基团。自由基对的组合产生1,2-二烷基烷基-2-羟基乙酮(2)和二环烷基甲醇(13)。在随后的反应中 三重激发的环烷甲醛使(2)的α-羟基次甲基氢抽象化,从而使自由基对歧化,生成环烷基甲醇(12)和二环烷基乙二酮(3)。无法检测到由Norrish II型工艺

    An object of the present invention is to provide a method for manufacturing an optically active menthol having fewer steps, which generates less environmentally polluting waste because a catalytic reaction is involved in all of the steps, and is capable of saving a production cost. The present invention relates to a method for manufacturing an optically active menthol, including the following steps: A-1) asymmetrically hydrogenating at least one of geranial and neral to thereby obtain an optically active citronellal, B-1) conducting a ring-closure reaction of the optically active citronellal in the presence of an acid catalyst to thereby obtain an optically active isopulegol, and C-1) hydrogenating the optically active isopulegol to thereby obtain an optically active menthol.

    Ir-catalyzed intramolecular silylation of secondary alkyl C-H bonds. (Hydrido)silyl ethers, generated in situ by dehydrogenative coupling of a tertiary or conformationally restricted secondary alcohol with diethylsilane, undergo regioselective silylation at a secondary C-H bond γ to the hydroxyl group. Oxidation of the resulting oxasilolanes in the same vessel generates 1,3-diols. This method provides a strategy
