A new method for the synthesis of 8-hydroxyisocoumarin is reported. 8-Hydroxyisocoumarin was synthesized from Meldrum's acid by Friedel-Crafts acylation, carbonyl protection, ester reduction and deprotection. The key intermediate 3-ethynyl-2-(hydroxymethyl)cyclohex-2-en-1-one was synthesized by acidic cycloaddition, aromatization of cyclohexanone ring and 2,3-dicyano-5,6-dichlorobenzoquinone (DDQ) oxidation. The structures were characterized by 1H NMR, 13C NMR, IR, and HRMS.

Key words: isocoumarin, 8-hydroxyisocoumarin, pyran, aromatization, synthetic method
