Sharma, MG; Vala, RM; Patel, HM in [Sharma, Mayank G.; Vala, Ruturajsinh M.; Patel, Hitendra M.] Sardar Patel Univ, Dept Chem, Univ Campus, Vallabh Vidyanagar 388120, Gujarat, India published Pyridine-2-carboxylic acid as an effectual catalyst for rapid multi-component synthesis of pyrazolo[3,4-b]quinolinones in 2020.0, Cited 38.0. Recommanded Product: 2,5-Dimethoxybenzaldehyde. The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7.
Green synthesis of pyrazolo[3,4-b]quinolinones was designed using bioproduct pyridine-2-carboxylic acid (P2CA) as a green and efficient catalyst. The multi-component reaction of aldehydes, 1,3-cyclodiones and 5-amino-1-phenyl-pyrazoles regioselectively produced pyrazolo[3,4-b]quinolinones in excellent yield (84-98%). Recyclization of the catalyst was also investigated. The electronic effect of the various substituents in aromatic rings indicated that the reaction proceeded through the carbocation intermediate. This newly designed protocol very quickly constructed products conventionally under milder conditions.
Recommanded Product: 2,5-Dimethoxybenzaldehyde. About 2,5-Dimethoxybenzaldehyde, If you have any questions, you can contact Sharma, MG; Vala, RM; Patel, HM or concate me.
