Abstract

2-Alkyl-3-(1-methyl-2-benzimidazolyl)-7-acyloxychromones were synthesized by the reaction of substituted or unsubstituted 2-(2,4-dihydroxyphenacyl)-1-methylbenzimidazoles with the acid chlorides and anhydrides of carboxylic acids. The products were converted into 2-alkyl-7-hydroxychromones as a result of acid hydrolysis.
