Revision of the Structure of a New Coumarin Isolated from Artemisia carviforia Wall
摘要:
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).

Revision of Structure of a New Coumarin Isolated from Artemisia carviforia WALL.
Four coumarins (1-4) were synthesized by routes shown in Charts 2-5, respectively. A proposed structure for a new coumarin isolated from Artemisia carviforia was incorrect, and the structure of coumarin should be represented by formula (3).
