Microwave irradiation of ortho‐allyloxy chalcones promotes a tandem sequence of Claisenrearrangement and 6‐endo‐trig‐cyclization. Olefin cross metathesis then furnishes prenylated flavonoids. The method has, inter alia, been applied to the synthesis of an angular chromene‐annellated natural product and its linear isomer. Both occur in medicinal plants indigenous in India and Nigeria respectively.
