An advantageous synthesis of new indazolone and pyrazolone derivatives
چکیده انگلیسی

The synthesis of new indazolone and pyrazolone derivatives starting from methyl anthranilate type substrates is presented. This general approach constitutes a novel and advantageous alternative for the synthesis of the target heterocycles, which implies the use of the environmentally friendly oxidizer PIFA. The synthetic design includes the oxidation of N-arylamides by the hypervalent iodine reagent to the corresponding N-acylnitrenium ions, which can be intramolecularly trapped by an amine moiety to furnish the title compounds by formation of a new N-N single bond.

The title compounds are obtained by an intramolecular PIFA-mediated N-N bond construction.
