A substoichiometric amount (10-20 mol%) of dibutyltin dichloride 1 was found to be effective for promoting the regioselective 2′-O-tosylation of adenosine 2 with TsCl in a one-pot manner, wherein a turnover step for tin dichloride 1 was involved. Dibutylc

2-Aminohexahydrobenzoxazole analogue 1a, related to trehazolin (2) was synthesized using the Ferrier reaction as a key step. The structural elucidation of this compound by NMR analysis indicated that it is an inseparable mixture of three components (1a-c) which in turn stems from the propensity of la to partially undergo both transcyclization (1a → 1b) of the aminooxazoline between the hydroxy group at the C-1 position of aminocyclitol in the aglycon moiety and the hydroxy group at the C-2 position of D-glucose moiety and successive transformation (1b → 1c) of the D-glucose moiety from a pyranose to a furanose structure.

An efficient method for the regioselective enhancement of the nucleophilicity of polyhydroxy compounds has been developed.Partial stannylation of carbohydrate with (Bu3Sn)2O and subsequent electrophilic attack with benzoyl chloride gave rise to regioselec
