Oxidative cyclization of o-hydroxy-ω-cinnamylideneacetophenones to 2-styrylchromones with potassium iodate-dimethyl sulphoxide
Singhi, Manasi,Grover, S. K.
, p. 1083 - 1084 (2007/10/02)
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.
