Three-component synthesis of new o-hydroxyphenyl-substituted pyrazolo[3,4-b]pyridines promoted by FeCl3

Three-component synthesis of new o-hydroxyphenyl-substituted pyrazolo[3,4-b]pyridines promoted by FeCl3

An efficient three-component synthesis of -hydroxyphenyl-substituted pyrazolo[3,4- ]pyridines from substituted salicylic aldehydes, -keto esters and 5-aminopyrazoles in the presence of FeCl is presented. Newly synthesized compounds were fully characterized by means of H NMR, C NMR, IR, HRMS and elem...

Zusammenfassung:An efficient three-component synthesis of -hydroxyphenyl-substituted pyrazolo[3,4- ]pyridines from substituted salicylic aldehydes, -keto esters and 5-aminopyrazoles in the presence of FeCl is presented. Newly synthesized compounds were fully characterized by means of H NMR, C NMR, IR, HRMS and elemental analysis.
