The inside back cover picture shows the controllable skeleton rearrangement of 3‐substituted cyclobutanones under basic conditions. In this paper, a series of 3‐substituted cyclobutanones with different Z group underwent skeleton rearrangement with the treatment of K 3 PO 4 and 18‐crown‐6 ether. Various lactones, lactams and acids were afforded in this concise reaction. More interestingly, an eight‐membered ring was produced with pentaflurophenyl group as a good leaving group. More details are discussed in the article by Lu et al . on page 1103—1106.
