A concise and versatile synthesis of 2-amino-3-cyanopyridine derivatives in 2,2,2-trifluoroethanol
摘要:
Trifluoroethanol (TFE) is found to be an efficient and recyclable medium in promoting one-pot, four-component coupling reactions of aldehydes, ketones, malononitrile, and ammonium acetate to afford the corresponding 2-amino-3-cyanopyridine derivatives in high yields. The solvent (TFE) can be readily separated from reaction products and recovered in excellent purity for direct reuse. (C) 2012 Elsevier B.V. All rights reserved.

for the growth of many pathogens and their inhibition leads to growth defects. Principal drawbacks in using CA inhibitors (CAIs) as antimicrobial agents are the side effects due to the lack of selectivity toward human CA isoforms. Herein we report a new class of CAIs, which preferentially interacts with microbial CA active sites over the human ones. The mechanism of action of these inhibitors was investigated
