Palladium-catalyzed carboannulation of propargylic carbonates and nucleophiles to 2-substituted indenes

J Org Chem. 2007 Feb 16;72(4):1538-40. doi: 10.1021/jo062377e.

Abstract

A new and efficient synthesis of 2-substituted indenes has been achieved via palladium-catalyzed carboannulation of propargylic carbonates with nucleophiles in good to excellent yields. A variety of nucleophiles were tolerated in this reaction.
