摘要

An efficient and multifunctional three component synthetic protocol was developed to synthesize ethyl 6-amino-4-aryl-5-cyano-2-propyl-4H-pyran-3-carboxylates from ethyl 3-oxohexanoate, malononitrile and corresponding aldehydes (1a-11a) using K_2CO_3 as a catalyst under water solvent in good yields. The derived compounds have been analyzed by IR and NMR (1D and 2D) spectra. Single crystal X-ray structural analysis of 2a, evidences the flattened-boat conformation of pyran ring and the phenyl group is nearly perpendicular to the pyran ring.
