ABSTRACT:
R or S-1-phenyl-1,3-propanediols having optical purity of 100% ee were obtained by recrystallization of R or S-1-phenyl-1,3-propanediols having optical purity of 20% ee to below 100% ee, the last diols are represented by the formula, ##STR1## It is possible to obtain optically pure 1-phenyl-3-propanediols from optically impure 1-phenyl-1,3-propanediols by a simple method.
