4-Benzoyl-5-phenyl-2,3-dihydrofuran-2,3-dione (1) reacts with aldehydes or ketones via the acylketene-intermediate (2) yielding the 1,3-dioxin-4-ones (3). The aldehyde derivatives (3 a-e) can be converted into the anilino-chalcone (5) or the anilino acrylic acid (6) by treating with aniline at 20 °C. 6 and diazomethane combine to the acrylic acid methyl ester (7), which by heating (200 °C) is cyclisized to the quinolin-4-ole (8). On the other hand, the keto derivatives 3f-h and aniline give the dibenzoyl acetic acid anilide (9).
