dithioacetals

The 1,2-addition of α-oxoketene dithioacetals with methallyl Grignard reagent afforded the carbinols 2. 5 and 6 respectively.

缩为五元和六元的α-氧代烯代缩与2-甲烯丙氯化镁反应得1,2-加成产物。

hydroxyl ketene dithioacetals possessing an allylalcohol moiety, as well as terminal bisalkylthio substituted alkene are a class of important intermediates in organic synthesis.

羟缩烯类化合物不仅含有烯丙醇结构单元,而且双键端位被双烷代,是有机合成中的一类重要的有机中间体。
