2,3-Dimercaptopropanol (BAL, I) is an effective detoxificating agent for heavy metals such as antimony^[1]. The conversion of tlis compound into its glucoside ("BAL intrav") results in increased water-solubility and diminished toxicity^[2]. However, it has not been possible to prepare this glucoaide in a chemical pure state. Moreover, it readily resinifies with less of activity. Attempts have been made in the present work to prepare some other sugar derivatives of thiols, and the preparation of some N-mercaptoacyl derivatives of D-glucosamine is now reported.
