β-Ketoester Dianions as Regiospecific Enolate Equivalents for N-Substituted Pyrrolidin-3-ones
Giles, Melvyn,Hadley, Michael S.,Gallagher, Timothy
, p. 1047 - 1048 (2007/10/02)
Double deprotonation of β-ketoester (6) gives dianion (7) which serves as a synthetic equivalent of the regiospecific ketone enolate (3), providing a synthetic entry to 2-substituted pyrrolidin-3-ones (9) and (10).
