and 1,7-bis(acylsilanes) have been prepared using a strategy of substitution of dihalo derivatives with a synthetic equivalent of the trialkylsilylcarbonyl anion. These bis(acylsilanes) could easily be converted, under Lewis acid activation, into cis-β-hydroxyacylsilanes or the corresponding α,β-unsaturated derivatives, by means of a completely stereoselective intramolecular aldol reaction.
使用合成等效的三烷基甲硅烷基羰基阴离子取代二卤代衍生物的策略,制备了一系列 1,6- 和 1,7-双(酰基硅烷)。在路易斯酸活化下,这些双(酰基硅烷)可以通过完全立体选择性的分子内醛醇反应轻松转化为顺式-β-羟基酰基硅烷或相应的 α,β-不饱和衍生物。
