摘要

Abstract: Condensation of phenols with but-2-enal and 3-methylbut-2-enal in the presence of phenylboronic acid in acetic acid–toluene solution leads to substituted and condensed 2H- chromenes, constituting a mild and advantageous complement to classical routes for this class of heterocycles. Key words: 2H-chromene, phenylboronic acid, condensation of phenols with unsaturated aldehydes
