A novel and efficient palladium catalyzed method was developed for the synthesis of wide range of pyrido[2,3-d]pyrimidines, using readily available β-bromovinyl/aryl aldehydes and 6-amino-1,3-dialkyluracils as the starting materials with good yields. This reaction proceeds via cascade imination/Buchwald-Hartwig cross coupling/cycloaddition reactions under microwave irradiation and solvent free conditions. This journal is
Four 7-ar-yl-substituted pyrido[2,3-d]pyrimidine-2,4(1H,3H)-diones: Similar mol-ecular structures but different crystal structures

Mol-ecules of 1,3-dimethyl-7-(4-methyl-phen-yl)pyrido[2,3-d]pyrimidine-2, 4(1H,3H)-dione, C16H15N3O2, (I), are linked by paired C - H...O hydrogen bonds to form centrosymmetric R 2 2(10) dimers, which are linked into chains by a single π-π stac
