摘要

Abstract Novel intermolecular and intramolecular generations of ortho-quinone methides and their formal [4+ 2]-cycloaddition reactions with olefins catalyzed by PtCl 4 and AuCl 3 under mild conditions have been developed. Good to excellent yields (up to 99%) and diastereoselectivity (up to> 99: 1) of the chromans were obtained. PtCl 4 was found to be effective and compatible with various functional groups present in the substrates. A ...
