Shamala, Devadas published the artcileZinc chloride catalyzed multicomponent synthesis of pyrazolopyridocoumarin scaffolds, SDS of cas: 86-51-1, the main research area is pyrazolopyridocoumarin preparation; hydroxycoumarin benzaldehyde alkyl aminopyrazole multicomponent condensation zinc chloride catalyst.
An efficient synthesis of a series of pyrazolopyridocoumarins I (R1 = Ph, 4-bromophenyl, 2,3-dimethoxyphenyl, etc.; R2 = Et, Me) is reported by condensation of 4-hydroxycoumarin, benzaldehydes R1CHO and 1-alkyl-5-amino-pyrazoles II in the presence of 10 mol% zinc chloride in ethanol under reflux conditions through one-pot reaction. The significant attraction of this protocol is being a simple procedure, mild reaction condition, and excellent yield. The mol. structure of the compound I (R1 = 2,3-dimethoxyphenyl; R2 = Et) is established by single crystal X-ray structure determination
