Abstract
Abstract Two racemic forms of 2-methyltartaric acid were prepared, and their optical resolutions were performed. Four optically active isomers were obtained. 2, 3-Dimethyltartaric acid was also prepared and separated into two isomeric optically inactive forms. The isomer with the higher melting point could be resolved into two optically active isomers, but the other, with the lower melting point, could not. The former was, therefore, assigned to the racemic configuration, and the latter, to the meso configuration.
