A new procedure for stereoselective synthesis of trisubstituted alkenes by an one-pot, three-component reaction of N-tosylated imines with α,β-acetylenic ketones and organozinc species CF3COOZnEt was described. This reaction system provides β-branched Morita–Baylis–Hillman adducts with excellent yields in absence of any catalyst.
描述了通过 N-甲苯磺酰化亚胺与 α,β-炔酮和有机锌物质 CF3COOZnEt 的一锅三组分反应立体选择性合成三取代烯烃的新方法。该反应系统在没有任何催化剂的情况下提供了具有优异产率的 β-支链 Morita-Baylis-Hillman 加合物。
