alkynyl ketones with 1,2-ethanedithiol in the presence of BF 3 -OEt 2 in methanol afforded the corresponding dithioacetal. Removal of the silyl group under basic conditions followed by palladium-catalyzed coupling reactions with aryl iodides yielded the corresponding propargylic dithioacetals in excellent yield.
在BF 3 -OEt 2 存在下,在甲醇中用1,2-乙二硫醇处理三甲基甲硅烷基取代的炔基酮,得到相应的二硫代缩醛。在碱性条件下去除甲硅烷基,然后与芳基碘化物进行钯催化的偶联反应,以优异的产率得到相应的炔丙基二硫代缩醛。
