with (phenylthio)acetic acid activated by bis(2-oxo-3-oxazolidinyl)phosphinicacid to give amide 15. Treatment of 15 with sodium hydride in tetrahydrofuran at 25 o C resulted in rapid conversion into a single diastereomer, 16. This same conjugate addition has been conducted at the sulfoxide oxidation level and also with a chiral sulfoxide to provide optically active compounds (Scheme VI). Conversion

Abstract A convenient procedure for the preparation of (trimethylsilyl)dimethylphosphinite was developed. The synthetic potential of the latter was exemplified by the preparation of dimethylphosphinoyl-derived nitriles, amines, acetone, acetic and acetoacetic acids as valuable building blocks for medicinal and materials chemistry.
