One-Pot Asymmetric Synthesis of Either Diastereomer of tert-Butanesulfinyl-protected Amines from Ketones
摘要:
[GRAPHIC]A one-pot method for the asymmetric synthesis of tert-butanesulfinyl-protected amines is described. Condensation of aryl alkyl and dialkyl ketones with tert-butanesulfinamide followed by in situ reduction with the appropriate reagent provides either diastereomer of the sulfinamide products in good yields and with diastereomeric ratios of up to 99:1.

A one-pot method for the asymmetricsynthesis of tert-butanesulfinyl-protected amines is described. The ketones bd2 are condensed with (R)-tert-butanesulfinamide bd1 and the tert-butanesulfinyl imine intermediates reduced in situ with NaBH4 to afford the sulfinamides bd4 in 66–86% yield and with drs from 90:10 to 97:3 for both aryl alkyl and dialkylketones. Ti(OEt)4 serves as both a water scavenger
