Acid-catalyzed dehydrative cyclization of 5-deoxy-L-manno-pentitol-1-yl)-2-heptulose bisphenylhydrazone and subsequent reflux with copper sulfate gave an anomeric mixture of 4-(5-deoxy-alpha,beta-L-arabinofuranosyl)-2-phenyl-2H-1,2,3-triazole C-nucleoside analogs. The mixture was separated by chromatography, and the anomeric compositions configurations of the components were determined by CD, NMR, mass spectroscopy, and acylation.
酸催化脱水环化 5-脱氧-L-甘露戊糖醇-1-基)-2-庚酮双苯腙，然后与硫酸铜回流，得到 4-(5-脱氧-α，β-L-阿拉伯呋喃糖基)-2-苯基-2H-1,2,3-三唑 C-核苷类似物的非对映混合物。混合物通过色谱法分离，通过 CD、NMR、质谱和酰化确定了各组分的非对映构型。
