An improved method for the tert-butanesulfinylation of diacetone glucose with tert-butanesulfinyl chloride is reported. The method is based on a beneficial effect of catalytic DMAP, which enhances both the rate of the reaction and the enantioselectivity of the process to give (R S)-diastereomer 2 R S with a 94 % de and in quantitative yield. (R...

A new type of chiral sulfinamide phosphinate catalysts with up to three stereogenic centers, readily accessible from commercially available starting materials, is reported. The naphthyl derivative SulPhos proved to be highly efficient in the organocatalytic asymmetric imine reduction, leading to a wide range of arylmethylamines in high yields...

The stereoselective addition of ethyl acetate enolate to the C═N bond of N-tert-butylsulfinylimines has been investigated in depth. A significant effect of the LHMDS amount and the N-sulfinylimine nature on the stereoselectivity of the process was observed. Conditions were found where sulfinylimines of differently substituted salicylaldehydes...
