Abba%act Enantiomeric purities and absolute configurations of chiral 8-propiolactones can be easily determined from the NMR spectra of diastereomeric solvates resulting from the interaction between the lactone and optically active 2,2,2 trifluoro-1 (9-anthryl) ethanol. Chiral 8-propiolactones subst
Mosher has pointed out (1) that although the optical rotatory diSperSion spectra of optically active o-hydroxy acids and their configurationally similar methyl ethers generally have identically signed Cotton effects, optically active cc-hydroxy-o-trifluoromethylphenylacetic acid, 3, and its configur
