چکیده
|
Zn-[2-boromophenyl-salicylaldimine-methylpyranopyrazole]cl2 {[zn-2bsmp]cl2}, as a schiff base complex, efficiently catalyzed the pseudo-six-component synthesis of tetrahydrodipyrazolopyridines by the condensation reaction of aryl aldehyde, hydrazine hydrate, ethyl acetoacetate and urea at 80 °c. urea was used instead of ammonium salts as a source of ammonia by in situ generation of ammonia, in the presence of a little amount of water.
