Abstract
The synthesis of substituted oxopiperazines, which may act as conforma tionally constrained peptide mimics, is reported. The synthesis is bas ed on the cyclization of sulfonamide dipeptides with dibromoethane as the 1, 2-dielectrophile. Alternatively, these mimetics were prepared v ia a Mitsunobu reaction.
