An one-pot, cascade assembly of polysubstituted cyclopentene was realized via the N-heterocyclic carbene (NHC)-catalyzed annulation of the in situ activated α,β-unsaturated carboxylic acid with 2-(2-oxo-2-arylethyl)malononitrile through the sequence of Michael addition, aldol condesation and decarboxylation. This method could serve as a new attractive strategy for the practical syntheses of multi-functionalized cyclopentene derivatives with broad substrate scope, readily availability of starting materials, mild reaction conditions, excellent yields and operational simplicity.

Key words: N-heterocyclic carbene (NHC), α,β-unsaturated carboxylic acid, 2-(2-oxo-2-arylethyl)malononitrile, poly-substituted cyclopentene, cascade reaction
