title: The Staudinger reaction with 2-imino-1,3-thiaselenanes toward the synthesis of C4 spiro-β-lactams.
abstract: The Staudinger ketene-imine [2 + 2] cycloaddition reaction for conversion of α-heteroatom-substituted exocyclic imines to C4 heterocyclic spiro-β-lactams has rarely been investigated due to their instability. Herein, we describe the Staudinger reaction between ketenes and α-selenium-substituted exocyclic imines to synthesize C4 spiro-β-lactams.
