the synthesis of truncated structures that contained the core stereochemical sites. Twelve stereochemical analogues were synthesized, their 1H and 13C NMR spectra were analyzed and four recurring stereochemical trends were distilled from the data. Applying the observed trends to the diastereomeric population pared the possible choices for the correct structure of mucoxin from 64 to 4. Synthesis of these
为了修改粘蛋白的结构分配,面对 64 种非对映体的可能性,我们求助于包含核心立体化学位点的截断结构的合成。合成了 12 种立体化学类似物,分析了它们的1 H 和13 C NMR 谱,并从数据中提取了四种重复出现的立体化学趋势。将观察到的趋势应用于非对映体群体,将正确结构的粘蛋白从 64 减少到 4。这些类似物的合成导致对粘蛋白正确结构的鉴定。
