propargyl bromide under Luche-Barbier conditions. Oxymercuration-cyclisation of the resulting hydroxyketones, followed by reductive or oxidative demercuration, provides functionalised spiroacetals, some of which are of insect origin.
在Luche-Barbier条件下,将酮醛5-oxo-9-癸烯(4)与烯丙基溴或炔丙基溴一起化学选择性加成到醛中。所得羟基酮的氧化汞环合,然后进行还原或氧化脱汞,提供官能化的螺缩醛,其中一些是昆虫来源的。
