development of a triflimide-catalyzed annulation of benzylic alcohols with allylsilanes for the synthesis of indane or tetralin structures is reported. In this fragment coupling reaction, complexity is built rapidly from readily available starting materials to yield diverse sets of products with up to three contiguous stereocenters. Indanes or tetralins can be generated from common precursors depending
据报道,用三氟甲酰亚胺催化的苄醇与烯丙基硅烷的环合反应可用于茚满或四氢化萘结构的合成。在这种片段偶联反应中,从容易获得的起始原料迅速建立了复杂性,以产生具有多达三个连续立体中心的多种产品。取决于所使用的烯丙基硅烷试剂的结构,茚满或四氢化萘可以从常见的前体中生成。几种木脂素天然产物的简洁合成突显了这种新设计方法的实用性。
