An N-heterocyclic carbene-catalyzed [8+3] annulation of tropone and enals via homoenolate

Vijay Nair, G; Manojkumar, P; Sreekumar, V; Suresh, E; Rajasekaran, T (American Chemical Society, 2006)

A novel protocol for the annulation of tropone to enals involving nucleophilic heterocyclic carbene (NHC) catalyzed homoenolate formation has been developed. Interestingly, the reaction led to bicyclic delta-lactones instead ...
N-heterocyclic carbene-catalyzed reaction of chalcones and enals via homoenolate: an efficient synthesis of 1,3,4-trisubstituted cyclopentenes

Vijay Nair, G; Sreekumar, V; Manojkumar, P; Suresh, E (American Chemical Society, 2006)

Nucleophilic heterocyclic carbene-catalyzed cyclopentannulation of enals and chalcones via homoenolate has been observed for the first time. Serendipitously, the reaction lead to a very efficient synthesis of 3,4-trans-d ...
Novel nucleophilic heterocyclic carbene mediated stereoselective conjugate addition of enals to nitrostyrenes via homoenolate

Vijay Nair, G; Sinu, C R; Beneesh, P B; Varghese, V; Anu Jose; Suresh, E (American Chemical Society, 2009)

A stereoselective Michael addition of homoenolate, generated from enals by nucleophilic heterocyclic carbene (NHC) catalysis, to beta-nitrostyrenes is reported for the first time. The products of this reaction obtained in ...
