  Microwave-assisted synthesis of substituted 2-amino-1H-imidazoles from imidazo[1,2-a]pyrimidines

  摘要：

  An efficient method for the synthesis of mono- and disubstituted 2-amino-1H-imidazoles via microwave-assisted hydrazinolysis of substituted imidazo[1,2-a]pyrimidines is reported. This protocol avoids strong acidic conditions and is superior to the classical cyclocondensation of alpha-haloketones with N-acetylguanidine. (C) 2009 Elsevier Ltd. All rights reserved.

  The invention refers to new compounds of formula (I), wherein A and B are selected from the group consisting of N and CH, with the condition that when A is N, B is N; R1 is selected from the group consisting of CH3 and NH2; R2 and R3 are selected from the group consisting of H, CH3, Br, Cl, COCH3 and OCH3; and R4, R5 and R6, are selected from the group consisting of H, F, Cl, Br, (C1-C3)-alkyl, trifluoromethyl, (C1-C3)-alkoxy and trifluoromethoxy. Compounds of formula (I) are prepared by reaction of a substituted aminoazine with a substituted 2-bromo-2-(4-R1-sulfonylphenyl)-1-phenylethanone in a polar solvent. These new compounds inhibit COX-2 with high selectivity over COX-1. They are useful for the treatment of inflamation and/or cyclooxygenase-mediated diseases, having the additional advantage of a reduced potencial for ulcerogenic effects.

  本发明涉及式(I)的新化合物，其中A和B选自由N和CH组成的组，条件是当A为N时，B为N；R1选自由CH3和NH2组成的组；R2和R3选自由H、 、Br、Cl、CO 和O 组成的组；以及R4、R5和R6选自由H、F、Cl、Br、(C1-C3)-烷基、三氟甲基、(C1-C3)-烷氧基和三氟甲氧基组成的组。式(I)化合物是由取代的氨基嗪与取代的 2-溴-2-(4-R1-砜基苯基)-1-苯乙酮在极性溶剂中反应制备而成。这些新化合物抑制 COX-2 的选择性高于 COX-1。它们可用于治疗炎症和/或环氧合酶介导的疾病，还具有减少致溃疡作用的潜力。
