  3-(2-硝基苯基)异恶唑和3-(硝基苯基)-4,5-二氢异恶唑催化加氢的有趣结果

  摘要：

  取代的 3-(2-硝基苯基) 异恶唑的钯碳辅助氢解，无论异恶唑环上的取代如何，都会导致硝基还原为氨基，同时伴随区域特异性闭环产生取代的 4-氨基喹啉。相比之下，类似的 3-(2-、3- 和 4-硝基苯基)-4,5-二氢异恶唑 (2-异恶唑啉) 的氢化导致硝基还原，仅保留二氢异恶唑环，得到相应的 3- (氨基苯基)-4,5-二氢异恶唑。

  Synthesis and biological evaluation of novel T-type Ca2+ channel blockers

  摘要：

  A small molecule library of piperazinylalkylisoxazole derivatives containing about 600 compounds was designed, synthesized and evaluated for blocking effects on T-type Ca2+ channel. Several ligands were identified to possess high inhibitory activity against the T-type Ca2+ channel. The compound 21 with trifluoromethyl substituents at C-3-position of phenyl group (W) and C-2-position of phenyl group (R-2) showed the highest inhibitory activity with IC50 value of 1.02 muM, which is comparable to that of mibefradil.

  The synthesis of a series of new 5-isoxazolpenicillins is described, which were obtained by coupling substituted isoxazoles with 6-APA. Concise large-scale synthesis of 3,5-disubstituted isoxazoles by 1,3-dipolar cycloaddition using copper(I) as catalyst was also investigated. Representative compounds were assayed for antimicrobial activities, showing satisfactory antimicrobial activities against Gram-negative

  hydrogenolysis of substituted 3-(2-nitrophenyl)isoxazoles, irrespective of substitution on the isoxazole ring, invariably leads to reduction of the nitro to the amino group with concomitant regiospecific ring closure to yield substituted 4-aminoquinolines. In contrast similar hydrogenation of 3-(2-, 3-, and 4-nitrophenyl)-4,5-dihydroisoxazoles (2-isoxazolines) results in reduction of the nitro group only
