This article deals with the synthesis of a new pyrazolo[4ʹ,3ʹ:5,6]pyrano[2,3-d]pyrimidine derivatives by the reaction of 1,4-dihydropyrano[2,3-c]-pyrazole-5-carbonitriles with ethyl cyanoacetate catalyzed by triethylamine (TEA) in ethanol under reflux conditions. All the synthesized compounds have been checked for their purity by melting point and TLC, and have been characterized through various spectroscopic techniques such as H and C NMR, IR, ESI-MS and elemental analysis. All synthesized…

N-propargylation reaction of substituted 4H-pyrano[2,3-d]pyrimidine derivatives under conventional, ultrasound- and microwave-assisted conditions
A series of substituted 4H-pyrano[2,3-d]pyrimidines were synthesized from corresponding substituted 4H-pyrans by ring-closing reaction with acetic anhydride or acetic acid in the presence of
