摘要

Abstract Debromination of N-benzyl 4-or 5-substituted α-bromo-α-p- toluenesulfonylglutarimides is achieved with 1, 8-diazabicyclo [5.4. 0] undec-7-ene (DBU) to give the N-benzyl 4-or 5-substituted α-p-toluenesulfonylglutarimides. The DBU/THF system is applied to a new methodology for the synthesis of bicyclic glutarimide skeleton in moderate yields.
