摘要
Compounds having a partial 2-pyridone structure or 3-pyridazinones can be selectively N-arylated with phenylboronic acids according to the procedure described by Chan and Lam. This procedure leads to N5-arylated imidazo[4,5-c]pyridin-4-ones, precursors of potent factor Xa inhibitors. In addition, the synthesis of N-aryl substituted pyrrole- and indole-2-carboxylic acid esters is described In the indole series this procedure offers a flexible entry in the synthesis of different 1,3-diaryl-2-carboxyindoles.
