Novel quinazoline ring synthesis by cycloaddition of N-arylketenimines with N,N-disubstituted cyanamides.
The reaction of N-aryl-substituted ketenimines with N,N-disubstituted cyanamides or (MeS)2C=N-CN under high pressure afforded 4-(N,N-disubstituted amino) or 4-(MeS)2C=N-substituted quinazoline derivatives, respectively. These products were formed by [4+2] cycloaddition between the aza-diene moieties of the N-arylsubstituted ketenimines and cyano groups. A 4-(unsubstituted amino)quinazoline deri...
متن کاملDesign, Synthesis, Characterization and Antimicrobial Evaluation of Novel 2,4-Disubstituted Quinazoline Derivatives
Resistance to bacterial and fungal strains towards existing antimicrobial agents has become an increasing incietment for research and development of new molecules to guard them. Quinazoline ring system could be clubbed into many ring systems which lead to potent and highly active compounds. In this work, series of eighteen compounds were docked into the ecKAS III binding site (1HNJ, PDB ID) by ...
متن کاملSynthesis and evaluation of 2,4-disubstituted quinazoline derivatives with potent anti-angiogenesis activities.
A series of 2,4-disubstituted quinazoline derivatives were designed and synthesized. The biological results showed that most of quinazoline derivatives exhibited potent antiproliferative activities against a panel of three tumor cell lines and a good inhibitory effect against the adhesion and migration of human umbilical vein endothelial cells (HUVECs). Among these compounds, 11d was the most p...
متن کاملSynthesis and antiepileptic activity of some novel semicarbazones containing 1,3,4-thiadiazole and quinazoline ring.
The incomplete seizure control with frequent adverse effects of current anticonvulsant drugs and the importance of semicarbazones, quinazolines and 2,5-disubstituted 1,3,4-thiadiazoles as anticonvulsant pharmacophore prompted us to carry out synthesis of three novel series of semicarbazones containing 1,3,4-thiadiazole and quinazoline ring. The chemical structures of these compounds were elucid...
متن کاملBridgehead nitrogen heterocycles which contain the quinazoline moiety -- synthesis and cycloaddition of 1,2-dihydroquinazoline 3-oxides.
A novel synthesis of 1,2-disubstituted 1,2-dihydroquinazoline 3-oxides 8 and the first ever examples of 1,3-dipolar trapping of these nitrones to homonuclear dipolarophiles is described. The new dipoles 8 reacted with N-methyl maleimide, generating diastereomeric adducts 14-16. In the reaction between 8 and dimethyl acetylenedicarboxylate, primary cycloadducts 17 and/or stable rearrangement pro...
