2,3-Heteroaromatic ring-fused cyclohexanones via heteroaromatic homo-Nazarov cyclization of donor–acceptor substituted cyclopropanes

Abstract

Heteroaryl 2-silylmethyl-substituted cyclopropyl ketones rearrange under Lewis acid conditions via heteroaromatic homo-Nazarov cyclization to form 2,3-heteroaromatic ring fused 4-t-butyldiphenylsilylmethyl-substituted cyclohexanones.
