Pyrrolidinones derived from (S)-pyroglutamic acid. Part 4. α, β-diaminopyrrolidinones
The electrophilic amination of a β-aminolactam to provide direct acess to conformationally constrained diamines was discussed. The β-aminolactams was found to be derived from the conjugate addition of O,N-dibenzylhydroxylamine to a highly activated α,β-un

Azasugar analogues: Conformationally restricted vicinal diamine derived from (S)-(-)-pyroglutamic acid
The preparation of a diamino substituted pyrrolidinone system in a diastereoselectively controlled manner is described. The procedure employed made use of electrophilic amination of a chiral bicyclic γ-lactam, which when subjected to sequential deprotecti
