✦ Synopsis


A versatile method for the solid-phase synthesis of differentially substituted quinazolin-4(3H)-ones has been developed using immobilized arylguanidines. The latter were obtained by treating the amino group of polymer-linked anthranilamide with isothiocyanates followed by coupling with secondary amines in the presence of DIC. Finally a cyclative cleavage strategy was applied to give the desired compounds in high yields and purities.

A solid-phase traceless synthesis of quinazolin-4-ones is described. An aldehyde functionalized resin was reductively aminated with primary amines, and the resin-bound secondary amine acylated with o-nitro-benzoic acids. The nitro group was reduced with tin(II) chloride, and the aniline acylated wit
