Maddila, Suresh published the artcileUltrasound mediated green synthesis of pyrano[2,3-c]pyrazoles by using Mn doped ZrO2, HPLC of Formula: 86-51-1, the main research area is pyranopyrazole carboxylate preparation green chem ultrasound; dimethylacetylenedicarboxylate malononitrile benzaldehyde hydrazine hydrate coupling zirconium oxide catalyst; carbonitrile pyranopyrazole preparation green chem ultrasound; acetoacetate malononitrile benzaldehyde hydrazine hydrate coupling zirconium oxide catalyst.
Mn doped zirconia is utilized as an environment-friendly and efficient catalyst for an ultrasound mediated four-component coupling reaction, containing dimethylacetylenedicarboxylate/ethyl acetoacetate, hydrazine hydrate, malononitrile, and aromatic aldehyde RC6H4CHO [R = 2-F, 4-Br, 3-OH, 2-OCH3, 2,3-(OCH3)2, 2,5-(OCH3)2, 2,4,6-(OCH3)3]. These reactions were performed under green solvent conditions, to yield pyrano[2,3-c]pyrazole-3-carboxylate derivatives I [R1 = C(O)OCH3] and pyrano[2,3-c]pyrazole-5-carbonitrile derivatives I (R1 = CH3) with good to excellent yields (88-98%). The main benefits of this process are short reaction times, easy work-up, reusability of the catalyst and no chromatog. purifications.
