Abstract
(+)-4-Methyl-4-phenyl-2-cyclohexenone ((+)-I), obtained by asymmetric synthesis, was chemically correlated to (S)-(+)-2-methyl-2-phenylbutanoic acid, whose absolute configuration is known. It was shown that (+)-4-methyl-4-phenyl-2-cyclohexenone ((+)-I) has (R) configuration. In determining the configuration, the optical ratation of optically pure (+)-4-methyl-4-phenyl-2-cyclohexenone ((+)-I) was estimated to be +130°in ethanol at D ray.
