Synthesis of chiral sulfinamido-sulfonamides and their evaluation as ligands for the enantioselective ethylation of aldehydes

A family of chiral sulfinamido-sulfonamide ligands have been synthesized from sulfinimines and has been evaluated as ligands for the enantioselective addition of diethylzinc to aldehydes with Ti(OiPr)4. The structure of these diamino compounds has been systematically modified to optimize the results.

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
