N-heterocyclic carbene catalyzed reaction of enals and 1,2-dicarbonyl compounds: Stereoselective synthesis of spiro gamma-butyrolactones

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

Nucleophilic heterocyclic carbene (NHC) catalyzed annulation of enals and cyclic 1,2-dicarbonyl compounds, opening a route to gamma-spirolactones, has been observed for the first time. The strategy works well with isatins, ...
