The reactions of mannopyranosyl dimethylphosphinothioates and alcohols using silver perchlorate as an activator in the presence of molecular sieves 4A in benzene at room temperature gave the 1,2-trans-α-mynnopyranosides in good yields.On the other hand, 1

1,2-cis-β-Mannopyranosides were obtained predominantly by reactions of mannopyranosyl dimethylphosphinothioate derivatives with several alcohols in the presence of iodine and a catalytic amount of triphenylmethyl perchlorate as the activator in benzene.

Stereoselective thermal glycosylation of a variety of alcohols with 2,3,4-tri-O-benzylα-L-rhamnopyranosyl chloride and 2,3,4,6-tstra-O-benzyl-α-D-mannopyranosyl chloride have achieved to give α-glycosides in high selectivity.
