ISOLATION AND SYNTHESIS OF TWO COUMARINS FROM MELAMPODIUM DIVARICATUM

Two new coumarin isomers have been isolated from Melampodium divaricatum and identified by spectral procedures as 8-hydroxy-7-(3'-methyl-2'-butenyloxy)coumarin (1) and 7-hydroxy-8-(3'-methyl-2'-butenyloxy)coumarin (2).The regioselective synthesis of each isomer was made by two different alkylation pathways confirming their structures.Key Word Index - Melampodium divaricatum; Heliantheae; Compositae; new coumarins; NMR; synthesis.

Revision of the structure of a new coumarin isolated from Artemisia carviforia wall

Four coumarins (1-4) were synthesized by the routes shown in Schemes 2-5, respectively. The previously proposed structure for a new coumarin isolated from Artemisia carviforia was incorrect; the structure of the coumarin is represented by formula (3).
