چکیده

The synthesis of 2,5-disubstituted 5,6-dihydro-lH-pyrido[l,2-a]quinazoline-l,6-diones (3) by reacting monosubstituted bis 2,4,6-trichlorophenyl malonates (1) with 3-aryl-3,4dihydro-2-methyl-4-quinazolinones (2) is described. Allylation of the pyridoquinazoline 3 c with allylbromide afforded the corresponding 3-allyloxy derivative 4. Certain generalizations of the cleavage processes of this series in the MS are reported.

An efficient route for the synthesis of a new class of pyrido[2,3-d]pyrimidine derivatives.

A new reaction of 4-arylidene-3-methylisoxazol-5(4H)-one or 4-arylidene-2-phenyloxazol-5(4H)-one with 2,6-diaminopyrimidin-4(3H)-one is described and a number of new pyrido[2,3-d]pyrimidine-4,7-dione derivatives are synthesized. This protocol has the advantages of good yields, broad substrate scope and simple work-up.

New nitrogenous compounds from Anisotes trisulcus.

Re-investigation of the methanolic extract of Anisotes trisulcus (Forssk.) Nees aerial parts led to the isolation of two new tricyclic quinazoline alkaloids, 8-amino-7,8,9,11-tetrahydro-6H-pyrido[2,1-b]-quinazoline-2,6-diol (4) and 8-amino-3,6-dihydroxy-7,8,9-trihydro-6H-pyrido[2,1-b]quinazoline-11-one (5), and two quaternary ammonium compounds, (dimethylamino)-N-(hydroxymethyl)-N,N-dimethyl me...

Concise synthesis of rare pyrido[1,2-a]pyrimidin-2-ones and related nitrogen-rich bicyclic scaffolds with a ring-junction nitrogen.

Pyrido[1,2-a]pyrimidin-2-ones represent a pharmaceutically interesting class of heterocycles. The structurally related pyrido[1,2-a]pyrimidin-4-ones are associated with a broad range of useful biological properties. Furthermore, quinolizinone-type scaffolds of these sorts with a bridgehead nitrogen are expected to display interesting physico-chemical properties. However, pyrido[1,2-a]pyrimidin-...

One-pot, Environmentally Benign Procedure for the Synthesis of tetrahydrotetrazolo[1,5-a]quinazolines Using [Bmim]Cl/AlCl3 as a Task-specific Ionic Liquid

A practical and green approach for the one-pot multicomponent synthesis of fused tetrazolo[1,5-a]quinazoline derivatives has been described via the condensation of 5- aminotetrazole, dimedone, and various aldehydes using 1-butyl-3-methylimidazolium tetrachloroaluminate [bmim]Cl/AlCl3, as a catalyst and task-specific ionic liquid medium. The catalyst was showed remarkable advantages in compariso...

A new synthetic route to original sulfonamide derivatives in 2-trichloromethylquinazoline series: a structure-activity relationship study of antiplasmodial activity.

We report herein a simple and efficient two-step synthetic approach to new 2-trichloromethylquinazolines possessing a variously substituted sulfonamide group at position 4 used to prepare new quinazolines with antiparasitic properties. Thus, an original series of 20 derivatives was synthesized, which proved to be less-toxic than previously synthesized hits on the human HepG2 cell line, but did ...
