Uncatalyzed reaction of phenols and naphthols with methyl cinnamates. A simple synthesis of 4-arylchroman-2-ones and 1-arylbenzo[f]chroman-3-ones

Article abstract of DOI:10.1055/s-1997-1293

4-Arylchroman-2-ones and 1-arylbenzo[f]chroman-3-ones can be prepared in moderate to good yields by reaction of phenols or β-naphthols with p-substituted methyl cinnamates in o-xylene under reflux.
