Synthesis of functionalized tetrahydro-dispiro[pyrazolone 4, 2′-pyran-5′, 4″-pyrazolone] scaffolds via an Oxa-Michael-initiated cascade [4 + 2] annulation reaction using pyrazoledione-derived MBH-alcohols

In this study, an efficient protocol was developed for synthesizing tetrahydro-dispiro[pyrazolone 4, 2′-pyran-5′, 4″-pyrazolone] scaffolds, using pyrazoledione-derived MBH alcohols and arylidene pyrazolones. The reaction proceeds through an oxa-Michael-initiated cascade [4 + 2] annulation under meta...
