Synthesis of thiodisaccharides or thioglycosides was performed by phase-transfer catalysis using phosphonium or ammonium salts.Starting from glycosyl halides, reaction with Na2S gave the corresponding thiodisaccharides with inversion of configuration at the anomeric centre.With unstable glycosyl halides, a solid-liquid system was used.Unsymmetrical thiodisaccharides and 1-thioglycosides were prepared by reaction of glycosyl halides with thiolate or 1-thioglucose under p.t.c. conditions.

A Lewis acid-catalyzed condensation between 2,3,4,6-tetra-O-acetyl-1-thio-α-D-glucopyranose and 1,3,4,6-tetra-O-benzyl-D-fructofuranose in dichloromethane, followed by a l.c. separation of the deprotected resulting disaccharides, led to 1-thiosucrose (β-D
