✦ Synopsis

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 configurationally similar methyl ether have oppositely signed Cotton effects.
