Abstract
A new technique for the elaboration of α-methylene-γ-butyrolactams hydroxymethylated at the β-position has been developed. This new synthetic approach is based upon the preliminary assembly of N protected and γ-carboxylated analogues. A subsequent reduction / elimination sequence and ultimate N-deprotection completed the synthesis of the titled compounds.
