Novel formation and crystal structure of 2-(2,2,2-trifluoroethylidene)-6-trifluoro-methyl-2,3-dihydro-4H-1,4-oxazin-3- ones from N-acetyl-N-alkyl-α-amino acids

The title compounds (2a-g) were formed from N-acetyl-N-alkyl-α-amino acids (1a-g) on treatment with trifluoroacetic anhydride in the presence of pyridine. The structure of the product (2a) was determined by single crystal X-Ray analysis.

Chiral phospholanes via chiral 1,4-diol cyclic sulfates

This invention relates to novel chiral 1,4-diol cyclic sulfates and their use as precursors in the preparation of chiral phospholane ligands, and chiral complexes useful as catalysts for carrying out enantioselective reactions.
