Abstract
The successful synthesis of pure crystalline vitamin A by Arens and van Dorp1 and by Isler et al.2 opened a new field in the chemical study of vitamin A. Thus, it is possible to synthesise various analogues of vitamin A in order to establish the relationship between chemical structure and vitamin A activity. A survey of recent publications on synthetic compounds bearing modified side chains led to the conclusion that although the terminal hydroxyl group might not be of utmost importance, the length and the general skeleton of the side chain could not be altered without a complete loss of activity. (cf. Table I.)
抽象
Arens和van Dorp1以及Isler等人2成功合成了纯结晶维生素A,这开创了维生素A化学研究的新领域。因此,可以合成各种维生素A类似物,以建立化学结构与维生素A活性之间的关系。对带有修饰侧链的合成化合物的最近出版物进行调查后得出结论,尽管末端羟基可能不是最重要的,但侧链的长度和总体骨架不能改变,否则将完全失去活性。(参见表I。)
