Different aromatic aldehydes and cinnamaldehyde undergo cross-aldol condensation with chroman-4-ones and1-thiochroman-4-ones in the presence of amberlyst-15 under microwave irradiation in solvent free condition to afford rapidly the corresponding
Use of imidazolium ionic liquids [Bmim][CF3COO] and [Bmim]OH as a catalyst for synthesis of 3-arylidene(thio)chroman-4-ones by the condensation of (thio)chroman-4-ones and aromatic aldehydes under microwave irradiation conditions. A series of 3-arylidene(thio)chroman-4-ones were obtained as the only product and considerable increase of yield was founded within short time. The products 3-arylidene(thio)chromanones were assigned the ( E)-configuration based on 1H NMR spectroscopic data.
