| description | The invention belongs to the technical field of medicine and sugar chemical synthesis, and particularly relates to a preparation method and application of peracetyl-protected 1-thioglucose and glucose1-mercaptan. The preparation method comprises the following steps of reacting peracetyl-protected glucose and potassium thioacetate in an organic solvent at the temperature of between normal temperature and 50 DEG C under the catalysis of boron trifluoride diethyl ether for 4-8 hours to obtain peracetyl-protected 1-thioglucose; and dissolving the prepared peracetyl-protected 1-thioglucose in dimethylformamide, and removing thioacetyl by using hydrazine hydrate to obtain peracetyl-protected glucose 1-mercaptan. The peracetyl-protected glucose 1-mercaptan can be used for further preparing auronofen and gliclazide thioglycoside analogues. The method disclosed by the invention is mild in reaction condition, simple and convenient to operate, low in synthesis cost, relatively green and high inyield, the auronofen is a |
