✦ Synopsis

Abstract

A new resolution of DL‐threonine into the optical antipodes is effected by fractional crystallization of the stereoisomeric brucine salts of L‐ and D‐N‐phthaloyl‐threonine in methyl‐cellosolve. The two salts mentioned posses extraordinarily different degrees of solubility in methyl‐cellosolve, and this allows the production of D‐ and L‐threonine by simple operations in very high yield.
