标题:钛催化的叔醇脱羟基反应
摘要:在此,我们报告了在温和反应条件下钛催化的脂肪族叔醇直接脱羟基反应,形成了 Barton 型脱氧产物.该协议容忍范围广泛的功能组,包括初级烷基氯和羰基.它允许二醇中的叔醇选择性脱羟基,并形成具有适度氘掺入的氘化产物.几种药物和天然产物(或其衍生物)的有效修饰突出了该方法的合成效用.

摘要:Disclosed are compounds suitable for use as raw materials which enable cis-olefin compounds useful as physiologically active substances such as the sex pheromones of various insects, or as intermediates for the synthesis thereof to be prepared on an industrial scale at a reasonable cost, and processes for the preparation of cis-olefin compounds by using the same. For this purpose, novel compounds (i.e., 1-halo-cis-3-tetradecenes) of the general formula (I) CH3(CH2)9CH=CH(CH2)2X(I)wherein X is a halogen atom, are used as raw materials for the preparation of cis-olefin compounds.
