allylide, a moderately stabilized telluronium ylide, generated from 3-trimethylsilyl- 2-propenyldiisobutyltelluronium bromide (3) with LiTMP, reacted with carbonyl compounds to afford trimethylsilylvinyl oxiranes in excellent yields with high syn stereoselectivity.
三甲基甲硅烷diisobutyltelluronium allylide,适度稳定的碲叶立德,从3-三甲基硅烷基-2- propenyldiisobutyltelluronium溴(生成3与LiTMP)中,用羰基化合物反应,得到环氧乙烷trimethylsilylvinyl在具有高优异的产率顺式立体选择性。
