Practical acylation of unprotected tartaric acid 1 by acyl chlorides to the corresponding monoacyltartaric acids 2 has been shown. Several unusual cases in the acylation of 1 are observed; it has been found that two routes of acylation are possible. In the benzoylation of 1, in addition to the expected products, the formation of a previously undescribed monobenzoyltartaric anhydride 7a is reported. An unusual DME cleavage during the course of acylation was also observed. © ARKAT USA, Inc. Source
