Construction of 3-allylidene-4-vinyltetrahydrofurans and 3-allylidene-4-vinylpyrrolidines via sequential domino allylation/olefination of C–C triple bonds
摘要:
An efficient method via sequential domino allylation/olefination of C-C triple bonds for the syntheses of five-membered heterocycles was developed by treatment 1,6-enynes with alkenes in the presence of a palladium catalyst. The configurations of the 1,3-dienes of the five-membered heterocycles are stereocontrolled. (C) 2011 Elsevier Ltd. All rights reserved.
