We reported relative green synthesis of 1-thioglycosides by straightforward reaction of per-O-acetylated glycoses with KSAc in EtOAc. Furthermore, the highly efficient method to synthesize per-O-acetylated glycosyl disulfide and glycosyl 1-thiol were developed. Based on this, the synthesis of auranofin was improved and two thioglucoside gliflozin analogues (possible SGLT inhibitors) were efficiently
