The preparation and the reactivity of the zincioallene 3 is described. This organometallic compound reacts with aldehydes to yield propargylic halohydrins with good diastereoselectivities. These halohydrins can easily be converted into propargylic oxiranes.
描述了锌基丙二烯 3 的制备和反应性。这种有机金属化合物与醛反应生成具有良好非对映选择性的炔丙基卤代醇。这些卤代醇可以很容易地转化为炔丙基环氧乙烷。
