Abstract

[Figure not available: see fulltext.] One-pot efficient copper-catalyzed approach for the synthesis of tetracyclic chromeno[4',3':4,5]pyrimido[1,2-b]indazolone and chromeno[4,3-d]-[1,2,4]triazolo[4,3-a]pyrimidine derivatives as a class of pharmacologically interesting compounds through the intramolecular domino condensation–aza-Diels–Alder reaction of aminoazoles and o-propargylated salicylaldehydes under reflux conditions has been described. © 2023, Springer Science+Business Media, LLC, part of Springer Nature.
