A new and efficient approach to benzocycles from cyclopropene derivatives is described. Deprotection by organolithiums and subsequent ring-opening cyclization of the related 2-cyclopropenyl phenyl or benzyl acetates generated benzofurans and isochromenes in one pot.
本文描述了一种从环丙烯衍生物合成苯并环体系的新颖、高效方法。用有机锂试剂脱保护后，相关的 2-环丙烯基苯基或苄基乙酸酯进行开环环化反应，一锅法生成苯并呋喃和异色烯。
