Abstract: Abstract A clean, cost-effective and practical approach has been described for the convenient synthesis of a library of 4-aryl-pyrazolo[5,6]pyrano[2,3-d]pyrimidines starting from a four-component condensation of ethyl acetoacetate, hydrazine hydrate, aromatic aldehydes, and barbituric/thiobarbituric acid in… read more here.
