    • Abstract


      A comparison of1H NMR spectra of acetoxycoumarin and alkoxycoumarin shows that an aromatic proton para to the site of difference undergoes a larger change in chemical shift. In absence of a para proton,-ortho protons undergo this change. These help in locating alkoxylation sites in naturally occurring coumarins.
