香豆酸甲酯衍生的1-苯甲酰胺基6-氧代-1,6-二氢吡啶-3-羧酸甲酯的环化反应:[1,2,4]三唑并[1,5- a ]吡啶环系统的组装
摘要:
利用衍生自廉价的,可商购的酰肼A和香豆酸甲酯B的新型中间体,完成了一系列稠合双环s- [1,2,4]三唑并[1,5- a ]吡啶1的有效三步合成。这种方法的一个显着特点是形成了二酰肼中间体2,而无需在1,2,4-三唑合成中形成氧化N–N键。由于结晶恶二唑鎓盐3所提供的杂质排斥,证明除了简单分离外,无需进一步纯化二酰肼2。。另外,所制得的高氯酸恶二唑鎓盐显示出优异的水分稳定性,这是该类型化合物中的异常特征。

DOI:10.1039/c5ra18386c
日期:——
We report herein a high-throughput methodology for the synthesis of 1,2,4-oxadiazole and 1,2,4-triazole small-molecule libraries using an integrated synthesis and purification platform.
The invention relates to a method of removing 3-deoxyglucosone and other alpha-dicarbonyl sugars from skin. The invention further relates to methods of inhibiting production and function of 3-deoxyglucosone and other alpha-dicarbonyl sugars in skin. The invention also relates to methods of treating 3-deoxyglucosone and other alpha-dicarbonyl sugars associated diseases and disorders of skin.
