Notes:
Carbon-13 spectral assignments of five pyrano [3,2-c] [1] benzopyran-5 (2H) - ones, five pyrano[2,3-c][1] benzopyran-5 (2H) - ones and five 2-methylfuro[2,3-c][1] benzopyran-4-ones and of 2-methylfuro [3,2-c][1]benzopyran-4-one and 4-(2-chloroallyl)-3-hydroxycoumarin were made from mutual correlations, 13C/1H coupling constant measurements and 2D X-H correlation analyses. High-resolution proton resonance assignments of these compounds are reported.
