Phenyl and/or tert-butyl α or β-D-glucopyranosyl sulfones were treated with lithium aluminum hydride and potassium hydroxide respectively to afford conveniently desulfonylated products (4 and 5). From the former reductive process was isolated the 2-deoxy-1,5-anhydro-D-glucitol derivative (4) as a major product and from the latter alkaline treatment was obtained the pyranoid-2-enono-δ-lactone derivative
分别用氢化锂铝和氢氧化钾处理苯基和/或叔丁基α或β-D-吡喃葡萄糖基砜,以方便地获得脱磺酰化产物(4和5)。从前一种还原过程中分离出主要产物2-脱氧-1,5-脱水-D-葡萄糖醇衍生物(4),从后一种碱处理过程中获得了吡喃类-2-烯醇-δ-内酯衍生物(6 )以相当高的收率有效地在单个过程反应中完成。
