Description

Application

Ellman′s Sulfinamides

(R)-(+)-2-Methyl-2-propanesulfinamide may be used to prepare N-(1-cyclohexylmethylidene)-2-methylpropane-2-sulfinamide via copper mediated condensation with cyclohexane carboxaldehyde. It may also be used to prepare (20E)-N-[t-butyl-(R)-sulfinyl]-3β-(t-butyldimethylsilyloxy)-pregn-5-en-20-imine, an intermediate for the development of androgen receptor antagonists.

Can be readily transformed into P,N-sulfinyl imine ligands through condensation with aldehydes and ketones, which can undergo iridium-catalyzed asymmetric hydrogenation of olefins.

Preparation of ß-chloro sulfinamides in a synthesis of chiral azridines. Also used to prepare an organocatalyst for enantioselective reduction of imines.

Useful reagent for synthesizing chiral amines.
