"In Situ" Generated "HCl": A Highly Efficient Catalyst for One-Pot Synthesis of 1H -Indazolo [1,2-b]phthalazine-1,6,11-triones and 1H- pyrazolo[1,2-b]phthalazine-5,10-diones under Solvent-Free Conditions

"In Situ" Generated "HCl": A Highly Efficient Catalyst for One-Pot Synthesis of 1H -Indazolo [1,2-b]phthalazine-1,6,11-triones and 1H- pyrazolo[1,2-b]phthalazine-5,10-diones under Solvent-Free Conditions

The rapid and environmental synthetic route to produce 1H-indazolo[1,2-b] phthalazine-1,6,11-triones and 1H-pyrazolo[1,2-b]phthalazine-5,10-diones derivatives have been developed via multi-component and one-pot reactions of various aldehydes, cyclic or acyclic 1,3-diketones with: i) phthalhydrazide or ii) phthalic anhydride-hydrazinium hydroxide using wet 2,4,6-trichlorotriazine (TCT) as catalyst under solvent-free conditions. Simple and mild reaction conditions, the use of a cheap catalyst and easy workup and isolation are notable features of this method.
