Synthesis of 2-Acetamido-2-deoxy-1,6-dithio-d-glucose and its Derivatives

Abstract

2-Acetamido-3,4-di-Oacetyl-2,6-dideoxy-6-S-acetyl-6-thio-d-glucopyranosyl chloride (III) was condensed with potassium thiolacetate, potassium ethylxanthate or thiourea to give three crystalline derivatives of 2-acetamido-2-deoxy-1,6-dithio-d-glucose. An attempt to prepare 2-acetamido-1,2,6-trideoxy-1,6-dimercapto-D-glucose (VII) from 2-acetamido-3,4-di-O-acetyl-1,2,6-trideoxy-1,6-di-S-acetyl-1,6-dithio-β-d-glucopyranose was described. 2-Acetamido-3,4-di-O-acetyl-1,2,6-trideoxy-1-mercapto-6-S-acetyl-6-thio-β-d-glucopyranose (VIII) was synthesized from the condensation product of III with thiourea.
