[formula: see text] Using triol 1 as a representative example of natural products containing two contiguous propionate units, 13C and 1H NMR databases for the stereochemical assignment of acyclic compounds have been created. Chemical shift increments due to the presence of additional functional groups as well as solvent effects are discussed.
[公式:见正文]使用三醇1作为含有两个连续丙酸酯单元的天然产物的代表性实例,已创建了13C和1H NMR数据库,用于无环化合物的立体化学分配。讨论了由于存在附加官能团以及溶剂影响而引起的化学位移增加。
