Spectral studies on coumarins and the determination of the constitution of ekersenin by total synthesis

Spectral studies on coumarins and the determination of the constitution of ekersenin by total synthesis
During the determination of the constitution of ekersenin isolated from Ekerbegia senegalensis, 8 isomeric monomethoxy-monomethylcoumarins were synthesized. These studies proved that ekersenin was 4-methoxy-5-methylcoumarin, a constitution with novel biosynthetic implications. Apparently ekersenin is the first example of natural coumarin biosynthesis involving only the polyketide route. Comparative spectral correlations on substituted coumarins are summarized.
