摘要

Two plus two equals a bicycle: A highly efficient acidcatalyzed intramolecular [2+2] cycloaddition of eneallenones affords strained bicyclo[n.2.0] frameworks, which contain vicinal all-carbon quaternary and tertiary centers (see scheme; Tf: trifluoromethanesulfonyl), under mild conditions with excellent yields and chemo-, regio-, and diastereoselectivities.
