  Synthesis and characterization of quinazoline derivatives: search for hybrid molecule as diuretic and antihypertensive agents

  摘要：

  To explore the pharmacological and structure-activity relationship of a series of N-substituted-(4-oxo-2-substituted-phenylquinazolin-3-(4H)-yl), substituted benzene sulfonamide derivatives (1-25) were synthesized from substituted anthranilic acids derived amino quinazolines and substituted benzene sulphonamides. All the synthesized compounds were evaluated for their diuretic (by Lipschitz et al. method), antihypertensive activity by non-invasive blood pressure (NIBP) using the tail-cuff method and anti-diabetic potential in rats. Six compounds showing significantly excellent activity were compared with metolazone, prazosin and diazoxide as standards. Compound N-[7-chloro-2-(4-methoxyphenyl)-4-oxoquinazolin-3(4H)-yl]-4 nitrobenzenesulfonamide (20) exhibited most potent of the series.

  Copper catalyzed CN bond formation/C–H activation: synthesis of aryl 4H-3,1-benzoxazin-4-ones

  摘要：

  We have developed a practical and efficient synthesis of 2-phenyl-4H-benzo[d][1,3]oxazine-4-one derivatives through copper catalyzed tandem reaction of 2-iodobenzoic acid with arylmethanamines under aerobic conditions. Compared to the literature methods toward the synthesis of 2-phenyl-4H-benzo[d][1,3]oxazine-4-one, the synthetic method reported in this Letter has broad substrate scope, mild reaction condition, and uses an inexpensive catalyst.

  efficient palladium-catalyzed carbonylative cyclization of N-substituted 2-iodobenzamides and 2-iodoanilides was investigated for the synthesis of phthalimides and benzoxazinones, respectively, by using phenyl formate as a CO source. The present catalytic protocol circumvents the use of an expensive phosphine ligand as well as solvent in the case of the phthalimide synthesis. Moreover, mild reaction conditions
