A cyclopropyl‐substituted 1,3‐bis(silyl enol ether) was prepared in two steps and subsequently employed in the cyclization with oxalyl chloride to give a cyclopropyl‐carbonyl substituted γ‐alkylidenebutenolide. The cyclization of the 1,3‐bis(silyl enol ether) with 1,3‐dielectrophiles afforded cyclopropyl‐carbonyl substituted phenols. The reactions proceeded with very good regioselectivity.
