A series of new N-(2-benzimidazol)(S)-α-aminoesters and the respective N-oxides have been prepared, and their spectral data discussed. The CD spectra of the aliphatic and aromatic amino ester derivatives of either series show sign reversal for the observed Cotton effect (CE) band. This chiroptical behaviour was rationalized as due to differences in conformational isomerism.
制备了一系列新的N-(2-苯并咪唑)(S)-α-氨基酯和相应的N-氧化物,并讨论了它们的光谱数据。任一系列的脂族和芳族氨基酯衍生物的CD光谱均显示出所观察到的Cotton效应(CE)谱带的符号反转。由于构象异构现象的差异,这种按摩疗法行为被合理化了。
