Highly diastereoselective [3+2] cycloadditions between nonracemic p-tolylsulfinimines and iminoesters: An efficient entry to enantiopure imidazolidines and vicinal diaminoalcohols

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
