Krief-Reich elimination over silicon-controlled rearrangement in β-seleno- γ -silyl alcohols, readily available from α-selenoaldehydes, 10 - 12. Usefulness of this protocol for the introduction of the allylsilane function α to the carbonyl group in cycloalkanones as well as for the preparation of unsymmetrically substituted allylsilanes is also reported.
描述了通过区域和立体控制的途径合成(E)-烯丙基三甲基硅烷的方法,是基于优先选择Krief-Reich来消除在β-硒代γ-甲硅烷基醇中由硅控制的重排,这很容易从α-硒醛中获得,10-12还报道了该方案对于将烯丙基硅烷官能团α引入环烷酮中的羰基以及制备不对称取代的烯丙基硅烷的有用性。
