We designed and synthesized quinazolin-2,4-dione-based hydroxamic acids to serve as selective competitive inhibitors of histone deacetylase-6 (HDAC6). The most potent and selective compound, 3d (IC50, 4 nM, HDAC6; IC50 > 10 μM, HDAC1

We report a Pd-catalyzed three-component reaction of 2-bromoanilines, carbon dioxide, and isocyanides. The combination of these two readily available C1-reactants, featuring a huge difference in kinetic and thermodynamic stability, is hitherto unprecedented in transition-metal catalysis. With this one-pot three-component reaction, N3-substituted quinazoline-2,4(1H,3H)-diones are obtained in moderate to high yields in a completely regio- and chemoselective manner. Our approach easily allows variation of the arene and N3-substitution pattern of the desired heterocycle. The formal synthesis of different APIs illustrates its practical applicability. In addition, the methodology also allows for a convenient and selective 13C-labeling through the use of 13CO2. This is illustrated for [2-13C]-2,4-dichloro-6,7-dimethoxyquinazoline synthesis, a key intermediate for several APIs.
One-pot Syntheses of Some New 2,4(1H,3H)-quinazolinedione Derivatives in the Absence of Catalyst

A facile, rapid and one-pot procedure for the synthesis of some new 2,4(1H,3H)-quinazolinediones is described. The method involves the one-pot condensation of isatoic anhydride, primary amine and carbonyl diimidazole (CDI) in the absence of organic or inorganic catalyst. It affords the corresponding product in high yield.
Syntheses of quinazoline-2,4-dione alkaloids and analogues from Mexican Zanthoxylum species

Quinazolinone and quinazolinedione derivatives are of considerable interest due to their wide array of pharmacological properties. In this paper we report the synthesis of ten quinazolinediones. The previous isolation of two of these compounds, namely 1-methyl-3-(2′-phenylethyl)-1H,3H-quinazoline-2,4-dione and 1-methyl-3-[2′-(4′-methoxyphenyl)ethyl]-1H,3H-quinazoline-2,4- dione, from the seed husks of Mexican Zanthoxylum species has been reported.
