A Simple and Efficient Diversity-Oriented Synthesis of New Substituted 3-(Arylamino)-6,7-dihydro-1H-indazol-4(5H)-ones by a KOH-Assisted One-Pot Reaction
A novel, simple, and straightforward combinatorial method for the synthesis of new substituted 3-(arylamino)-6,7-dihydro-1H-indazol-4(5H)-one derivatives has been developed. The synthesis was achieved via a one-pot three-component reaction of aromatic isothiocyanates, substituted 1,3-cyclohexanediones, and hydrazine hydrate in dimethyl sulfoxide as a polar aprotic solvent. This methodology has the
