  Fluorinated Benzyloxyphenyl Piperidine-4-carboxamides with Dual Function against Thrombosis: Inhibitors of Factor Xa and Platelet Aggregation

  摘要：

  A series of benzyloxy anilides of nipecotic (5, 6) and isonipecotic (7, 8) acids were synthesized and assayed in vitro as inhibitors of ADP-induced platelet aggregation and the blood coagulation enzymes factor Xa (FXa) and thrombin (FIIa). An exploration of effects of the amidine group attached at the piperidine nitrogen,position and substitution (F, phenyl) of the benzyloxy group, and addition of fluorine/s on the second (distal) phenyl ring, led us to single out some promising isonipecotamide derivatives 7. Addition of meta-F and para-CF3 on the distal phenyl ring resulted in a 6-to-18-fold enhancement of the FXa potency and in 2-to-4-fold increase of the antiplatelet potency, the last depending to a large extent upon lipophilicity. Two congeners of N-{[3-(1,1'-biphenyl-4-yl)methoxy]phenyl}piperidine-4-carboxamide (7m and 7p) proved to be potent FXa-selective inhibitors (K-i = 130 and 57 nM, respectively) and antiplatelet agents and were identified as leads for developing new dual function antithrombotic drugs.

  Copper-Catalyzed Arylation and Alkenylation of Polyfluoroarene C−H Bonds

  摘要：

  An efficient, copper-catalyzed method for the arylation, alkenylation, and benzylation of polyfluoroarenes has been developed. Arenes containing two or more fluorine substituents on the aromatic ring can be efficiently functionalized. The best results are obtained by using a combination of copper iodide catalyst, phenanthroline ligand, aryl bromide or aryl iodide coupling partner, and DMF or DMF/xylene mixed solvent.

  The present invention is a one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using a combination of aryl halides, a substrate, and a copper salt as catalyst. This method allows faster introduction of complex molecular entities, a process that would otherwise require many more steps. This invention is particularly relevant for the organic synthesis of complex molecules such as, but not limited to, pharmacophores and explosives.
