Stereocontrolled Synthesis of Enantiopure Substituted 4-Aminopyrrolidin-2-ones
摘要:
The highly diastereoselective conjugate addition of N-benzylhydroxylamine and benzylamine to alpha,beta-unsaturated lactam 3 provided an efficient entry to enantiopure (4S,5S)-4-amino-5-hydroxymethylpyrrolidin-2-ones. (C) 1997 Elsevier Science Ltd.

α,β-Unsaturated γ-lactams undergo regio- and stereoselective 1,3-dipolar cycloadditions with N-benzyl and N-methyl nitrones and can act as acceptors in conjugateaddition of N-methylhydroxylamine. These reactions give access to highly functionalized pyrrolidones.
