Abstract

Functionalized arenes are prepared by chelation-controlled [3+3] cyclization/cyclopropane opening reactions of 1-trimethylsilyloxy-1,3-butadienes with benzyloxy- or methoxy-substituted 1,1-diacyclopropanes. Mixed chromanes-isochromanes are prepared by using 1,3-bis(silyloxy)-1,3-butadie nes containing a remote chloride group.
