Abstract Oxidation of chromanones (1a-i) and 2-spiro-chromanones (j-m) using [hydroxy(tosyloxy)iodo] benzene in refluxing acetonitrile as well as using ultrasound via dehydrogenation and 2,3-alkyl migration provides a convenient route for the synthesis of chromones (2a-i), tetrahydroxanthones (2j,k) and their higher homologues (21,m). The ultrasound also enhances substantially the rate of above transformations
