The preparation of α,β-unsaturated ketones and α,β-epoxyketones from readily accessible 1-haloenynes are described. The procedures involve the regio- and stereoselective hydroboration of 1-halodienylboranes, and oxidative work-up under appropriate conditions of the dienylboranes formed.
描述了从易于获得的1-卤代烯炔制备α,β-不饱和酮和α,β-环氧酮的准备方法。该方法涉及1-卤代二烯基硼烷的区域选择性和立体选择性氢硼化反应,以及在适当条件下对形成的二烯基硼烷进行氧化处理。
