  2-aminoquinazolinones derivatives from inexpensive reactants. A simple and efficient method was developed for the synthesis of N-aroyl-N′-arylguanidines under mild conditions by an unexpected demethylation–addition cascade reaction of readily available N-cyanoimidates with aryl amines. Moreover, 1-aryl-2-aminoquinazolin-4(1H)-ones and 2-(arylamino)quinazolin-4(3H)-ones can also be prepared by selective cyclization

  the Dimroth rearrangement in aqueous ethanolic sodium hydroxide gave exclusively the regioisomers, 2-(N-arylamino)quinazolin-4-ones. The regioselective synthesis of N-aryl-substituted 2-aminoquinazolin-4-ones can be further applied to the synthesis of benzimidazo[2,1-b]quinazolin-12-ones.

  在对-TsOH存在下，在t- BuOH中，在回流下，邻氨基苯甲酸甲酯与N-芳基氰酰胺的反应主要得到3-芳基喹唑啉-4-酮。相比之下，相同的反应物与TMSCl在60°C的t- BuOH中反应，然后在乙醇氢氧化钠水溶液中进行Dimroth重排，仅得到区域异构体2-（N-芳基氨基）喹唑啉-4-酮。N-芳基取代的2-氨基喹唑啉-4-酮的区域选择性合成可以进一步应用于苯并咪唑并[2，1- b ]喹唑啉-12-酮的合成。

• Reversible Inhibitors of the Gastric (H+/K+)-ATPase. 5. Substituted 2,4-Diaminoquinazolines and Thienopyrimidines

  Quinazolines bearing a secondary 4-(arylamino) substituent demonstrate an SAR for inhibition of the gastric (H+/K+)-ATPase different from the previously described 3-acylquinolines, suggesting that, although these compounds are also K+-competitive, they probably bind to the enzyme in a different orientation. Compounds bearing a tertiary 4-(arylamino) substituent, however, in particular 4-(N-methylarylamino), appear to possess an SAR quite similar to the 3-acylquinolines. We show that this arises from the effect of the N-methylation, which is to orientate the 4-(arylamino) substituent syn to C-5, analogous to the 3-acylquinolines. Compounds possessing both a 4-(N-methylarylamino) substituent and a 2-(arylamino) substituent proved to be very potent, K+-competitive inhibitors of K+-stimulated ATPase activity with K-i values down to 12 nM. Some compounds also proved to be effective inhibitors of stimulated acid secretion in both the rat and dog when dosed intravenously. However, although a number of these demonstrated activity after oral administration in the dog, the level and variability precluded further evaluation.
