The absolute configuration of secondary alcohols can be determined by NOE between the diastereotopic protons of the lactam and the protons of the alcohol moieties in some 1-(alkoxymethyl)-methyl-2-pyrrolidone-5-carboxylate derivatives. Two simple methods based on conformational analysis and 1H NMR data have been developed. The main conformer, in all cases, was established by means of MM, semi-empirical
仲醇的绝对构型可以通过内酰胺的非对映体质子与1-(烷氧基甲基)-甲基-2-吡咯烷酮-5-羧酸酯衍生物中醇部分的质子之间的NOE确定。已经开发了两种基于构象分析和1 H NMR数据的简单方法。在所有情况下,主要一致性是通过MM,半经验和从头算的方法确定的。
