Palladium-Catalyzed Carbonylative Reactions of 1-Bromo-2-fluorobenzenes with Various Nucleophiles: Effective Combination of Carbonylation and Nucleophilic Substitution

systematic study on the carbonylative transformation of 1-bromo-2-fluorobenzenes with various nucleophiles has been performed. Different types of double nucleophiles, such as N-N, N-C, O-C, and N-S, can be effectively applied as coupling partners. The cor

Synthesis of quinazolin-4(1 H)-ones via amination and annulation of amidines and benzamides

Quinazolinones have broad applications in the biological, pharmaceutical and material fields. Studies on the synthesis of these compounds are therefore widely conducted. Herein, a novel and highly efficient copper-mediated tandem C(sp2)-H amination and annulation of benzamides and amidines for the synthesis of quinazolin-4(1H)-ones is proposed. This synthetic route can be useful for the construction of quinazolin-4(1H)-one frameworks.

1,2,3-Benzotriazin-4-ones and Related Systems. Part 6. Thermal and Photolytic Decomposition of 3-Arylideneamino-, 3-Imidoyl-, and 3-Heteroaryl-1,2,3-benzotriazin-4-ones

Thermal decomposition of 3-arylideneamino- and 3-imidoyl-1,2,3-benzotriazin-4-ones in solution gives 2-arylquinazolin-4-ones and 1,2-diaryl-1,4-dihydroquinazolin-4-ones, respectively.In the latter decompositions phenanthridones are also formed in minor but substantial (20percent) yield.Possible mechanisms to account for these products are discussed.Photolysis of the 3-arylideneamino-derivatives in methanol provides a useful synthesis of aldehyde o-(methoxycarbonyl)phenylhydrazones. 3-(α-Pyridyl)- and 3-thiazol-2-yl-1,2,3-benzotriazin-4-one undergo thermal decomposition to pyridoquinazolin-11-one and thiazoloquinazolin-5-one, respectively.
