Cycloaddition des N-phényl-C-arylnitrilimines sur des dérivés de la 2-benzylidènebenzo[b]tiophèn-3(2H)-one (thioaurones)
Written by sctunisie no comments1,3 dipolar cycloaddition of N-phenyl-C-arylnitrilimines with 2-arylidenebenzo[b]thiophen-3-ones, leads to the formation of pyrazoles after opening of the thiophenonic ring followed by a nucleophile substitution with a second molecule of N-phenyl-C-arylnitrilimine with high yield.
