Herein, we have disclosed a feasible approach to access oxygen bridged tricyclo fused cyclopropane derivatives via visible light mediated photoredox catalyzed 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.
