The influence of different 5-alkyl-substituted resorcinols on the formation of 2,2-dimethylchroman-4-ones is examined experimentally and theoretically. Structures are fully assigned by means of experimental and theoretical C and H NMR chemical shifts. Based on experimental and theoretical calculations of Friedel-Crafts acylation, it is possible to explain the formation of 2,2-dimethyl-5-hydroxychroman-4-ones
通过实验和理论研究了不同 5-烷基取代的间苯二酚对 2,2-二甲基色满-4-ones 形成的影响。通过实验和理论 C 和 H NMR 化学位移完全指定结构。基于 Friedel-Crafts 酰化的实验和理论计算,可以解释 2,2-二甲基-5-羟基色满-4-ones 和/或 2,2-二甲基-7-羟基色满-4-ones 的形成。还报告了对它们作为大麻素受体配体的生物活性的评估。
