GENERATION AND DIELS-ALDER REACTIONS OF N1-SUBSTITUTED PYRAZOLE-4,5-QUINODIMETHANES

The cycloaddition of o-quinodimethanes (9-11) generated in situ from the 4,5-bisbromomethylpyrazole derivatives (6-8), with several dienophiles leads to the formation of the cycloadducts (12-20).These Diels-Alder reactions are also examined on the basis o

The pyrazole analogue of ortho-quinodimethane: Generation and cycloaddition reactions

The hitherto unknown 1-benzoyl-4,5-dihydro-4,5-dimethylene-3-phenyl-1H-pyrazole (the pyrazole analogue of ortho-quinodimethane) has been generated in solution and trapped with symmetrical and unsymmetrical dienophiles.
