摘要

Abstract 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 13 C and 1 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 and/or 2, 2-dimethyl-7- ...
