Popis: 4-Amino-4′-nitrodiphenylsulphide and 4-amino-2′-nitrodiphenyl sulphide (I) were smoothly condensed with 2-methyl-3,1-benzoxazin-4-one (II) to produce the corresponding 2-methyl-3-diphenylsulphidoquinazol-4-ones (III). 2-Styryl-3-diphenylsulphidoquinazol-4-ones (IV) were prepared by heating III with the appropriate aromatic aldehydes using piperidine as a basic catalyst. Compounds IV oxidised easily in a hydrogen peroxide-glacial acetic acid mixture to produce the corresponding sulphones (V). The constitution of some of the prepared products is discussed in the light of their infrared and ultraviolet spectra. The biological activities of some of these compounds were tested.
