Oxidative cyclization of o-hydroxy-ω-cinnamylideneacetophenones to 2-styrylchromones with potassium iodate-dimethyl sulphoxide

o-Hydroxy-ω-cinnamylideneacetophenones (1) have been found to undergo oxidative cyclization to the corresponding 2-styrylchromones (2) in satisfactory yields by heating them with potassium iodate in dimethyl sulphoxide.

A modified synthesis of 2-styrylchromones

2-Hydroxy-ω-cinnamylideneacetophenones (3a-e) have been obtained by condensation of 2-hydroxyacetophenones (1) with cinnamaldehyde (2) in the presence of barium hydroxide.Oxidative cyclisation of the compounds 3a-e with iodine in dimethyl sulphoxide provi
