The very efficient addition of α,α‐difluoro‐α‐(trimethylsilyl)acetamides to aldehydes, ketones and N‐(tert‐butanesulfinyl)imines is described. The reaction is promoted by a catalytic amount of tetra‐n‐butylammonium diphenyltrifluorosilicate (TBAT) and high yields, as well as very high stereoselectivities in the case of N‐(tert‐butanesulfinyl)imines, are achieved. The synthetic potential of this method

Addition of ketene acetals to sulfinimines derived from homochiral N-tert-butanesulfinamide using various Lewis acids furnishes derivatives of aspartic acid in diastereomeric ratios up to 97:3. Following an easy removal of the N-tert-butanesulfinyl chiral auxiliary, optical active beta-amino esters are obtained.

the Rh(I)-catalyzed addition of arylboronic acids to N-tert-butanesulfinyl iminoesters has been developed for the asymmetric synthesis of arylglycine derivatives. This method provides high yields (61-90%) and diastereoselectivities (>98:2) for a variety of functionalized arylboronic acids. The N-sulfinyl arylglycine ester products are versatile intermediates for further transformations, including

A cationic palladium-complex-catalyzed addition of arylboronic acids to N-tert-butanesulfinyl iminoacetates to yield the optically active arylglycine derivatives with moderate to good yield and high diastereoselectivity was developed. This reaction provides a convenient and efficient method for the synthesis of arylglycine derivatives.
