Abstract
Abstract A series of isobutyl 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates (1–9) have been synthesized by the multicomponent reaction (MCR) between isobutyl ethylacetoacetate, aryl aldehydes and malononitrile using BF3:OEt2 as catalyst. The derived compounds have been analyzed by IR and NMR (1D and 2D) spectra. Single crystal X-ray structural analysis of 1, evidences the flattened-boat conformation of pyran ring.
