developed a reaction that affords the selective preparation of hexahydro-2H-pyrido[2,1-a]isoquinoline dienes, allenes, or alkenes via an intramolecular Heck cyclization of an aryl chloride with an alkyne. Tricyclic isoquinoline core structures of this nature are difficult to access by alternative methods. The unsaturated product formed can be partially controlled by choice of ligand and reaction solvent
我们已经开发了一种反应,该反应可通过芳基氯化物与炔烃的分子内Heck环化选择性制备六氢2 H-吡啶并[2,1- a ]异喹啉二烯,丙二烯或烯烃。这种性质的三环异喹啉核心结构很难通过替代方法获得。形成的不饱和产物可以通过选择配体和反应溶剂来部分控制。
