Abstract
An optical resolving reagent comprising at least one of compounds represented by the following formulae (1) and (2) (1) (2) (wherein Rto Reach represents hydrogen or Calkyl; Rrepresents optionally substituted Calkyl, optionally substituted Calkenyl, formyl, or acyl; and Rrepresents Calkyl; provided that the molecule represented by the formula (1) is of the cis configuration with respect to Rand OR); and a method of optically resolving with the optical resolving reagent an alcohol having an asymmetric carbon atom in the molecule and represented by the formula (3): (R)(R)(R)COH (wherein R, R, and Reach represents hydrogen or optionally substituted Calkyl, provided that at least one of R, R, and Ris not hydrogen). The method of optical resolution is highly suitable for general purposes. By the method, a mixture of optical isomers of any of various alcohols can be optically resolved easily and industrially advantageously.
