Abstract: A new multicomponent reaction, namely, a one-pot transformation of salicylaldehydes, 2-aminoprop-1-ene-1,1,3-tricarbonitrile, and 2-pyrazolin-5-ones in the presence of triethylamine as the catalyst in a minimum amount of propanol leads to the previously unknown substituted 2,4-diamino-5-(5-hydroxy-3-methyl-1H-pyrazol-4-yl)-5H-chromeno [2,3-b]-… read more here.
