A totally protected di-O-benzyl derivative of triacetonlactose dimethyl acetal was transformed into a 4'-hexeno disaccharide by elimination of acetone with t-BuOK in DMF and subsequently in 5'-C-methoxy derivative by oxidation with MCPBA in methanol as a solvent. The hydrolysis of this latter compound affords 2,6-di-O-benzyl-L-arabino-aldohexosos-5-ulose, which by intramolecular aldol condensation with DBU gives an inosose that was stereoselectively reduced to epi-inositol. Therefore our synthetic strategy offers a new and simple method to transform lactose into carbocyclic monosaccharide analogues. 相似文献
