quinolines were synthesized and evaluated as in vitro inhibitors of Mycobacterium tuberculosis (M. tuberculosis) growth. Structure-activity relationship (SAR) studies leaded to potent antitubercular agents, with minimum inhibitory concentration (MIC) values as low as 0.3 μM against M. tuberculosis H37Rv reference strain. Furthermore, the lead compounds were active against multidrug-resistant strains
2-b]pyridazines through AlCl3 induced C–C bond formation reactions. A wide variety of 6-aryl substituted azolopyridazines was reacted with 3,6-dichloropyridazine to give 7-pyridazinyl substituted pyrrolopyridazines regioselectively in good to excellent yield. The mechanism and regiochemistry of the reaction along with applications of the methodology are discussed.
我们描述了通过AlCl 3诱导的CC键形成反应对6,7-二取代的吡咯并[1,2- b ]哒嗪进行新型合成的详细研究。使多种6-芳基取代的偶氮哒嗪与3,6-二氯哒嗪反应,以区域选择性好至极佳的产率得到7-哒嗪基取代的吡咯并哒嗪。讨论了反应的机理和区域化学以及该方法的应用。

Oxazoles and pyrazines are fundamental heterocycles that widely found in natural products or drugs. In this work, a selective strategy for oxazoles and pyrazines synthesis using α-bromo-1-phenylethanone and ammonium acetate as starting materials was reported. This methodology features mild reaction conditions, readily accessible starting materials and good chemoselectivity. Mechanistic study indicates
