The Regioselectivity of the 1,3-Dipolar Cycloaddition of α-Carbonylformonitrile N-arylimides To Benzylideneacetone and β-Diketones
Albar, Hassan A.

The cycloaddition of the ethoxycarbonylformonitrile N-arylimides 2 to benzylideneacetone afforded two regioisomers, 5-acetyl- and 4-acetyl-dihydropyrazole but the cycloaddition of 2 to benzoylacetone afforded two regioisomers, 4-acetyl- and 4-benzoylpyrazole.Also, some pyrazolopyridazin-7-one and pyrazolopyridazinderivatives were synthesized.

The cycloaddition of C-ethoxycarbonyl-N-arylnitrilimines 3 and their C-acetyl analogs 4 to α,β-unsaturated ketones 5 give predominantly the 5-acyl-4-aryl-2-pyrazoline derivatives 8 and 9 respectively.The structures of the cycloadducts 8 and 9 were support
