Abstract/Summary

[15-(CH3)-C-13-H-2]-Dihydroartemisinic acid (2a), [15-(CH3)-H-2]-dihydroartemisinic acid (2b) and [15-(CH3)-C-13]-dihydroartemisinic acid (2c) have been obtained in good yield and high isotopic enrichment by a reconstructive synthesis from artemisinin. These labelled compounds were designed to be used in biosynthetic experiments to determine the origins of artemisinin and other sesquiterpene natural products from Artemisia annua.
