Add to ORKGABSTRACT — Synthesis of dihydrocoumarin derivatives from methyl trans-cinnamate is described. The reaction can be carried out as a simple one pot reaction using acid catalyst. Firstly, methyl trans-cinnamate was converted into cinnamic acid via hydrolysis reaction with alkaline. Secondly, esterification reaction of cinnamic acid was carried out by using an acid catalyst p-toluensulfonic acid with phenol, o-cresol, p-cresol which lead to the production of 4-phenylchroman-2-one, 8-methyl-4-phenylchroman-2-one, and 6-methyl-4-phenylchroman-2-one
