Synthesis of enantiopure vicinal diaminoesters and ketopiperazines from N-sulfinylimidazolidines

A short and efficient synthesis of mono- and bicyclic ketopiperazines bearing methoxycarbonyl substituents is described. The route entails selective protection and solvolysis of N-sulfinylimidazolidines to provide vicinal diaminoesters with the nitrogen a
