Synthesis of potential fungicides based on N-(3-furanyl)pyrrolecarboxamides and N-(3-furanyl)pyrazolecarboxamides
摘要:
An efficient synthesis of novel N-(3-furanyl)pyrrolecarboxamides and N-(3-furanyl)pyrazolecarboxamides is presented starting from furan-3-carboxylic acid. Two complementary strategies to 2-aryl-3-furanamines with directed ortho lithiation, functionalization of the 2-position, and subsequent cross-coupling reaction as key steps were developed. Acylation of these intermediates with appropriate acid chlorides led finally to the target compounds.
