literature review some curious inconsistencies in the free radical bromination of picolines were noted. To achieve a better understanding of the mechanisms and regioselectivity we reran these reactions, extending our work to unsymmetrical lutidines using N-bromosuccinimide in limiting amount. Characterization of the products was done with GC/MS and H NMR. The regioselectivity of bromination in unsymmetrical
在一篇文献综述中,人们注意到甲基吡啶的自由基溴化过程中存在一些奇怪的矛盾之处。为了更好地理解其机理和区域选择性,我们重新进行了这些反应,并使用有限量的N-溴代琥珀酰亚胺将工作扩展到不对称的二甲基吡啶。用GC / MS和1 H NMR对产物进行表征。在不对称的二甲基吡啶中溴的区域选择性表明环中的氮被感应失活。2,3、2,4和2,5二甲基吡啶对溴的竞争导致溴化在距离环中N最远的甲基中进行。3,4-亮氨酸仅显示4,4-二溴化产物。

antitubercular thienopyrimidine tool compound that suffers from metabolic instability (MLM t1/2 < 1 min), was utilized to assess the predictive power of our new MLM stability model. The S-substituent was removed, a set of commercial reagents was utilized to construct a virtual library of 411 analogues, and our MLM stability model was applied to prioritize 13 analogues for synthesis and biological profiling
