Abstract: Novel chromonyl phosphonic acid 3, diethyl chromonyl phosphonate 4, and diethyl chromonyl pyridinyl phosphonate 5 were obtained from treatment of 2-cyano-3-(4-oxo-4H-chromen-3-yl) prop-2-enamide (2) with phosphorous acid and its diesters. Also, an efficient route to functionalized… read more here.
