The treatment of sulfinyl chlorohydrins with KO-t-Bu in THF generates epoxy vinyl sulfoxides that undergo an efficient base-induced rearrangement to generate enantiopure hydroxy 2-sulfinyl dienes. This novel process takes place with high chemo- and stereoselectivity. The chirality at sulfur effectively controls the geometry of the trisubstituted alkene.
在THF中用KO- t- Bu处理亚磺酰氯醇会生成环氧乙烯基亚砜,这些环氧亚砜会进行有效的碱诱导的重排,从而生成对映纯的羟基2-亚磺酰基二烯。这种新颖的过程具有很高的化学选择性和立体选择性。硫的手性有效地控制了三取代烯烃的几何形状。
