    Description / Table of Contents: Zusammenfassung Die Fusion von 2-Acetamidonikotinsäure mito-Toluidin,p-Bromanilin odero-Chloranilin ergab die entsprechenden 3-Aryl-2-methyl-pyrido[2,3-d]pyrimidin-4(3H)-one (4) und die 8-Aza-Analogen von 3-Aryl-2-methyl-4-chinazolinonen zusammen mit 2-Aminonikotinsäure. 2-Methyl-3-(2-methylphenyl)-pyrido[2,3-d]pyrimidin-4(3H)-on (4a), das 8-Aza-Analog von Methaqualon, wurde mittels Kondensation mit einigen aromatischen Aldehyden zu den 2-substituierten Styryl-Derivaten6 umgesetzt. Die Reaktion mit monosubstituierten Bis-2,4,6-trichlorphenylmalonaten ergab tricyclische 10-Aza-5,6-dihydro-3-hydroxy-5-(2-methylphenyl)-2-substituierte 1H-Pyrido[1,2-a]quinazolin-1,6-dione (8).
    Notes: Abstract The fusion of 2-acetamidonicotinic acid witho-toluidine,p-bromoaniline oro-chloroaniline afforded the corresponding 3-aryl-2-methyl-pyrido-[2,3-d]pyrimidin-4(3H)-ones (4), the 8-aza analogs of 3-aryl-2-methyl-4-quinazolinones, alongside 2-aminonicotinic acid. 2-Methyl-3-2(2-methylphenyl)-pyrido[2,3-d]pyrimidin-4(3H)-one (4a), the 8-aza analog of methaqualone, was converted to the 2-substituted styryl derivatives6 by condensation with some aromatic aldehydes and to the tricyclic system, 10-aza-5,6-dihydro-3-hydroxy-5-(2-methylphenyl)-2-substituted-1H-pyrido [1,2-a] quinazoline-1,6-diones (8) by reaction with monosubstituted bis-2,4,6-trichlorophenyl malonates.

    Notes: Several 3-ketocoumarins with alkoxy or dialkylamino substituents in the 7 position, which are efficient sensitizers for crosslinkable polymers, were evaluated as photoinitiators. Proper combinations of certain derivatives of these ketocoumarins with activators such as amines, acetic acid derivatives, and alkoxypyridinium salts gave quantum yields for initiated radical polymerization much higher than that obtained from the Michler's ketone/benzophenone combinations. For each class of activators the dependence of the efficiency of polymerization on the redox properties of the ketocoumarins is explained in terms of charge transfer or electron transfer from the activator to the excited ketocoumarin (acetic acid and amine activators, respectively) or electron transfer in the opposite direction (pyridinium salt activators).
