The influence of the triphenyl-methyl grouping on optically active esters and ethers

| Summary: | The investigation of a number of optically active menthyl and octyl esters and ethers of mono-, di- and tri-phenyl substituted derivatives has shown that whilst there is a progressive change as we pass from the phenyl to the diphenyl derivatives the direction of change is reversed When a third phenyl group is introduced. This irregularity can be best explained as a space effect, since a similar fall in rotation is observed with the L-menthyl ester of ?-phenyl valeric acid and with the introduction of a phenyl group into the ortho position in L-menthyl benzoate. |
