The chemo‐ and stereocontrolled functionalization of conjugated sulfinyl dienes in a cascade process that involves a conjugate addition, diastereoselective protonation and a [2,3]‐sigmatropic rearrangement is reported. Enantioenriched 1,4‐diol and 1,4‐aminoalcohol derivatives are obtained in a very straightforward manner. Further functionalization of these structures, including highly stereoselective...
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(O i Pr) 4 . The structure of these diamino compounds has been systematically modified to optimize the results.
