Microwave irradiation under solvent-free conditions induced 3-styrylchromones to undergo Diels–Alder cycloaddition reactions with N-methyl- and N-phenylmaleimide as well as with other dienophiles. In some of these reactions the cycloadducts underwe

Four polyhydroxylated 2-styrylchromones, structurally related to flavones and cinnamic acid, have been studied. An SC derivative with OH groups only at positions 3' and 4' on the styryl moiety and another SC bearing an additional OH group at position

A novel route for the synthesis of 1-aryl-9H-xanthen-9-ones is reported. This methodology involves the condensation of 2-methylchromone with cinammaldehydes leading to (E,E)-2-(4-arylbuta-1,3-dien-1-yl)-4H-chromen-4-ones. The final step was the elect

The bromination of 2-styrylchromones, bearing electron neutral substituents, with two molar equivalents of piridinium tribromide gave 2-(2-aryl-1,2-dibromoethyl)chromones and 3-bromo-2-(2-aryl-1,2-dibromoethyl)chromones. The presence of electron-dona
