Carboxylate-substituted Nitrones as Aldehyde Synthons for the Addition of Ketone Enolates
Schlecht, Matthew F.
, p. 1239 - 1241 (2007/10/02)
The addition of a ketone enolate to an ester-substituted nitrone gives an adduct, which upon Hofmann degradation can be elaborated to give a γ-keto-α,β-unsaturated ester, the formal product of a directed aldol condensation.
