Photocatalyzed Energy Transfer for Atom Economical Synthesis of O‐Bridged Tricyclo‐Fused Cyclopropane Derivatives

Abstract

AbstractHerein, we have disclosed a feasible approach to access oxygen bridged tricycle‐fused cyclopropane derivatives via visible light mediated photocatalyzed energy transfer process. This protocol describes one step multi‐fused ring formation under mild reaction conditions to furnish a wide range of the fused cyclopropane derivatives in moderate to high yields with excellent diastereoselectivities.
