A Complete <sup>1</sup>H and <sup>13</sup>C NMR Data Assignment for Three 3-[Substituted methylidene]-1<i>H</i>,3<i>H</i>-naphtho-[1,8-<i>cd</i>]-pyran-1-ones

A combination of 1D and 2D NMR techniques, including HMQC, HSQC, <sup>1</sup>H-<sup>1</sup>H COSY and HMBC, was used to provide completely assigned <sup>1</sup>H and <sup>13</sup>C NMR data for the structures of three 3-[substituted methylidene]-1<i...
