Abstract

Development of a simple new methodology for the synthesis of (E)-3-benzylidenechroman-4-ones using methyl 3-aryl-3-hydroxy-2-methylenepropanoates, the Baylis–Hillman adducts derived from methyl acrylate, and the application of this methodology for the synthesis of the methyl ether of bonducellin, an important natural product, and 3-(4-methoxybenzylidene)-6-methoxychroman-4-one, an antifungal agent, are described.
