terminal double bonds. The 1H and 13C NMR spectra were assigned for 15 new compounds, including E‐Z isomers (all‐E, 13Z, 9Z and 9Z,13Z) of retinoids containing an ethyl ester and car‐boxylic acid polar end groups, and also the (all‐E)‐isomer of the retinoids with an alcohol and aldehyde polar end‐groups and five C15 intermediates. The assignments were based on long‐range 1H13C heteronuclear 2D experiments
合成了一类新的维生素 A 类似物(类视黄醇),其中含有一个二亚甲基桥,以保持末端双键的 6-s-反式构象。1H 和 13C NMR 谱被指定为 15 种新化合物,包括含有乙酯和羧酸极性端基的类视黄醇的 E-Z 异构体(全 E、13Z、9Z 和 9Z、13Z),以及(具有醇和醛极性端基和五个 C15 中间体的类视黄醇的 all-E)-异构体。这些分配基于远程 1H13C 异核 2D 实验。
