Synthesis of new 1H-indazoles through Diels-Alder transformations of 4-styrylpyrazoles under microwave irradiation conditions

Microwave irradiation under solvent-free conditions induces 1-acetyl-4-styrylpyrazoles to undergo Diels-Alder cycloaddition reactions with N-methyl- or N-phenylmaleimide to give tetrahydroindazoles in good yields and with high selectivities, With conventi

Efficient microwave-assisted synthesis of tetrahydroindazoles and their oxidation to indazoles

N-Acetyl-styrylpyrazoles undergo Diels-Alder cycloaddition reactions with N-methylmaleimide under solvent-free conditions to give the corresponding tetrahydroindazoles in good yields and high selectivity. On heating, these reactions do not occur or afford
