Abstract The reaction of d -gluconamide with benzoyl chloride and pyridine gave a complex mixture from which ethyl or methyl 2,3,5,6-tetra- O -benzoyl- d -gluconate ( 5 and 6 ) crystallized after treatment with ethanol or methanol, respectively. These esters were formed by alcoholysis of 2,3,5,6-tetra- O -benzoyl- d -glucono-1,4-lactone ( 4 ), which was isolated by column chromatography, together with
摘要d-葡糖酰胺与苯甲酰氯和吡啶的反应生成了复杂的混合物,乙醇或甲醇处理后使2,3,5,6-四-O-苯甲酰基-d-葡糖酸乙酯或甲酯结晶(5和6) , 分别。这些酯是通过2,3,5,6-四-O-苯甲酰基-d-葡萄糖酸-1,4-内酯(4)的醇化反应形成的,然后通过柱色谱法与五-O-苯甲酰基-d分离当使用过量的苯甲酰氯时,-葡糖醛腈(7),五-O-苯甲酰基-d-葡糖酰胺(8),N-苯甲酰基-戊基-O-苯甲酰基-d-葡糖酰胺(9)和苯甲酰胺。苯甲酰化亚氨基内酯中间体(3)的形成和水解解释了4和苯甲酰胺的分离。
