title: Three-component one-pot approach to synthesize benzopyrano[4,3-d]pyrimidines.
abstract: A novel benzopyrano[4,3-d]pyrimidine scaffold was generated via a three-component one-pot reaction from iodochromone, alkyne, and an amidine through a Sonogashira coupling, condensation, and cycloaddition. This combinatorial synthetic approach provides an efficient, easy construction of a diversified heterocyclic compounds library.
