  An efficient synthesis of β,γ,γ-trisubstituted-α-diethoxyphosphoryl-γ-lactams: a convenient approach to α-methylene-γ-lactams

  摘要：

  A general and efficient method for the preparation of beta,gamma,gamma-trisubstituted-alpha-phosphono-gamma-lactams is presented for the first time. This approach is based on the Michael addition of diethyl acetamidomalonate to methyl (E)-3-aryl-2-(diethoxyphosphoryl)acrylates. Application of the phosphono-lactams obtained for the preparation of alpha-methylene-gamma-lactams is also reported. (C) 2013 Elsevier Ltd. All rights reserved.
