Simple, convenient, and green synthetic protocols have been developed for the one pot synthesis of 2,3-disubstituted quinazolin-4(3H)-ones and 2-styryl-3-substituted quinazolin-4(3H)-ones under catalyst and solvent free conditions.
A Rh-catalyzed chelation-assisted C6-selective C–Hactivation/alkylation of 2-pyridones with readily available alkyl carboxylic acids or anhydrides is introduced. The reaction proceeds via substrate decarbonylation. This approach merges C–H functionalization with readily available anhydrides, allowing for the efficient synthesis of various C6-alkylated 2-pyridones with good functional group tolerance

complexes of some polydentate ON, OO and ONO donors in the form of 2-methyl-3-substituted (3H)-quinazolin-4-ones have been synthesized and studied. The reactionbetween RuCl2(DMSO)4 and the uninegative bidentate ligands yielded complexes of the type Ru(DMSO)2(OO)2 (OO = MHQ, PHQ, MHEQ, MHPQ or MCMQ), displacing only two DMSO groups along with chlorides, whereas the neutral bidentate ligands gave
合成了一些多齿ON,OO和ONO供体的钌(II)配合物,它们以2-甲基-3-取代的(3 H)-喹唑啉-4-酮的形式存在,并且研究过。RuCl 2(DMSO)4与非负二齿配体之间的反应产生Ru(DMSO)2(OO)2类型的配合物(OO= MHQ,PHQ,MHEQ,MHPQ或MCMQ),仅取代了两个DMSO基团以及氯化物,而中性双齿配体给出RuCl 2(ON)2(ON= MAQ,PAQ,MANQ,PANQ,MAAQ,MAPQ,MPQ或PPQ),取代了所有DMSO基团。然而,具有O = N = O供体的单负性齿状配体(MHAQ)生成了钌(II)的双螯合物。
