Abstract
2,3:4,6-Di-O-isopropylidene-d-allopyranose can be conveniently prepared from d-glucose via a synthetic sequence, which includes Mitsunobu inversion at O-3, di-O-isopropylidenation of phenyl-1-thio-d-alloside and anomeric deprotection on treatment with NBS/CaCO3.
摘要
2,3:4,6-二-O-异亚丙基-D-阿洛吡喃糖可通过一个合成序列由D-葡萄糖方便地制备，该序列包括O-3位的光延反转、苯基-1-硫代-D-阿洛糖苷的二-O-异亚丙基化以及用NBS/CaCO₃处理时的端基脱保护。
