Structural Elucidation of a Hydrolysis Product from Derivatives of Allofuranose
摘要
Abstract
1,2-O-(1-methylethylidene)-3-C-methylnitro-α-D-allofuranose(2)was obtained through selective deprotection of1,2;5,6-Di-O-isproplidene-3-C-methylnitro-α-D-allofuranose(1)underanacidic condition. C-3 nitrostyrenes(3)was synthetizedthrough Moffatt dehydration from compound1underanacidic condition.A hydrolysis product 1,2-O-(1-methylethylidene)-3-C-methylnitro-α-D-glocufuranose(2')which hada reversedC-3 configuration wasobtained by an unexpected oxa Michael addition.Compounds2and2'were C-3 diasteroisomers.Compound2'was characterized withNMR spectroscopy techniques, including1HNMR,13CNMR,DEPT-135,1H-1H COSY, gHSQC and gHMBC.1H and 13Cchemical shiftsof compound2'were also fullyassigned. The molecular structure of compound2'was determined.关键词
