Investigation of the alkylation of nitroazoles with ?-haloketones by13C,15N, and14N NMR
摘要:
General methods have been worked out for the alkylation of nitroazoles with bromoacetone, bromoacetophenone, and diazoacetone in homogeneous media and by phase-transfer catalysis. The structures of the N-acetonylazoles were established by C-13, N-15, and N-14 high-resolution NMR spectroscopy.
Disclosed herein are pyrazole glucokinase activators of the formula (I)
useful for the treatment of metabolic diseases and disorders, preferably diabetes mellitus.

the synthesis of nitroazole-based energeticmaterials, giving rise to a new family of highly dense and oxygen-rich energeticmaterials. They were characterized by IR spectroscopy, NMR spectroscopy, elemental analysis, DSC, and X-ray diffraction. These new molecules exhibit highdensities, moderate to good thermal stabilities, acceptable impact and frictionsensitivities, and excellent detonation properties
一种新的氮杂环的N-官能化策略被用于合成基于硝基唑的高能材料,从而产生了新系列的高密度和富氧高能材料。通过红外光谱,核磁共振光谱,元素分析,DSC和X射线衍射对它们进行了表征。这些新分子显示出高密度,中等到良好的热稳定性,可接受的冲击和摩擦敏感性以及出色的爆炸特性,这表明它们可能作为高能材料或氧化剂。有趣的是,在四唑基CHNO高能材料中,化合物5迄今为止的最高测量密度为1.97 g cm -3。5c到目前为止,它是第一个也是唯一一个具有正OB的杂环CHNO高能盐。与高度爆炸性的HMX相比,化合物5和6表现出出色的爆炸特性(38.5 GPa,9.22 km s -1; 37.0 GPa,9.05 km s -1)。具有高OB,具体冲动5,图5b,图5c和图6C都优于那些AP和ADN作为纯化合物,和氧化剂/铝的比值/ PBAN(%)为80:20:0或80:13 :7.此外,计算结果,BDE,M
