Synthesis of Some 5,6,7,8-Tetrahydro-4-cinnolone Derivatives and 1-Methyl-3-arylacetyl-4,5,6,7-tetrahydroindazoles

2-Arylidene-3-oxo-2,3,4,5,6,7-hexahydrobenzofurans 2 react with hydrazine hydrate to afford 5,6,7,8,-tetrahydro-4-cinnolones.By methylation, these compounds gave the corresponding N-1 and N-2 methyl derivatives.The mesoionic compounds are obtained, accompanied by 3-arylacetyl-4,5,6,7-tetrahydroindazoles upon reaction of 2 with methylhydrazine.
