Highly selective syntheses of d-talopyranosides and d-gulopyranosides have been achieved by utilizing the multiplier effects of substrate control and catalyst control. Through the combination of an O-benzoyl-protected substrate and the AD-mix-β system, the d-talopyranoside was obtained in a ratio of 96:4. In contrast, the d-gulopyranoside was obtained in a ratio of 3:97 through the use of an O-tert-butyldimethylsilyl-protected substrate and AD-mix-α.
