Sulfonamide ligands from chiral aziridines - Application to the titanium-mediated addition of diethylzinc to benzaldehyde
2002 (English)In: European Journal of Organic Chemistry, ISSN 1434-193X, E-ISSN 1099-0690, no 18, 3179-3188 p.Article in journal (Refereed) Published
A modular approach was developed for the preparation of chiral, enantiopure sulfonamide ligands with C-1, C-2, and C-3 symmetry by ring opening of chiral N-sulfonylaziridines with ammonia, primary amines, and diamines. The new ligands were assessed in the titanium-mediated addition of diethylzinc to benzaldehyde, giving the product with selectivities up to 76% ee.
