Abstract

Alkaline treatment of 2-acetamido-2-deoxy-3,4:5,6-di-O-isopropylidene-aldehydo-D-glucose, or of the analogous D-mannose derivative, gave the same crystalline material, unambiguously identified as 2-acetamido-2,3-dideoxy-alpha-D-erythro-hex-2-enofuranose (3) by n.m.r. and mass spectrometry, and crystallography. Treatment of 3 with methanol in acidic medium gave methyl 2-acetamido-2,3-dideoxy-alpha,beta-D-erythro-hex-2-enofuranoside (11). The identical compound was obtained from Chromogen I under identical conditions.

摘要

对2-乙酰氨基-2-脱氧-3,4:5,6-二-O-异亚丙基-醛基-D-葡萄糖或类似的D-甘露糖衍生物进行碱性处理，得到了相同的晶体物质，通过核磁共振、质谱和晶体学明确鉴定为2-乙酰氨基-2,3-二脱氧-α-D-赤式-己-2-烯呋喃糖（3）。在酸性介质中用甲醇处理3得到甲基2-乙酰氨基-2,3-二脱氧-α,β-D-赤式-己-2-烯呋喃糖苷（11）。在相同条件下从显色原I中得到了相同的化合物。
