-(methylsulfonyl)- and 3,4-di- O - p -tolylsulfonyl- D -mannitol and their 1,2,5,6-tetraacetates have been synthesized and crystallized. By the action of an excess of methanolic barium methoxide during 2 h at 25°, each of these compounds is converted into 2,3:4,5-dianhydro- D -iditol, the structure of which is assigned on the basis of chemical and physical properties, including n.m.r. spectroscopic evidence
摘要合成并结晶了3,4-二-O-(甲基磺酰基)-和3,4-二-O-对甲苯磺酰基-D-甘露糖醇及其1,2,5,6-四乙酸酯。在25°C下2小时内,通过过量甲醇甲醇钡的作用,将这些化合物中的每一种转化为2,3:4,5-二氢-D-ID醇,其结构根据化学和化学式确定。物理性质,包括核磁共振光谱证据。
