Synthesis of a few New 2'-Hydroxy-2-benzoyl-3- arylacrylophenones, 3-Benzoyl-2-arylchromones and 5-Benzoyl-1 ,2-dihydro-4-(2-hydroxyphenyl)- 6-aryl-2-thiopyrimidines

2'-Hydroxy-2-benzoyl-3-arylacrylophenones (2) have been prepared by the conden­sation of appropriate . β-diketone (1) and aromatic aldehyde. The acrylophenones thus obtained were oxidised with SeO₂, to get the respective 3-benzoyl-2-arylchromones (3). These on reaction with thiourea gave 5-benzoyl-1,2-dihydro-4-(2-hydroxyphenyl)-6- aryl-2-thlopyridines (4). The identification of these compounds have been established on the basis of chemical analysis and ir and nmr spectral data.
