A new procedure for the asymmetric synthesis of imidazolidines and vicinal diamines is reported. The 1,3-dipolar cycloaddition between nonracemic p-tolylsulfinimines and azomethine ylides generated in situ from aiminoesters and LDA produces N-sulfinylimid

The treatment of enantiopure N-sulfinyl-N′-benzyldiaminoalcohols with diethyl oxalate and sodium methoxide followed by reduction with BH3 affords enantiopure 1-benzyl-2,3-disubstituted piperazines. A related sequence produces substituted monoke
