Carbanion addition to acetylenes: An efficient stereoselective route to α-methylene-γ-lactams
Patra,Maiti,Chatterjee,Chakravarty
, p. 1363 - 1366 (2007/10/02)
Intramolecular addition of carbanions, derived from the acetylenic amides (5b,d), (7) and (9) has been shown to be highly stereoselective leading to the α-methylene-γ-lactam derivatives (6a,b), (8a,b) and (10).
