Irregular Monoterpene Constituents of Artemisia tridentata cana. The Isolation, Characterization, and Synthesis of two Chrysanthemyl Derivatives

Epstein, William W.,Klobus, Michael A.,Edison, Arthur S.

, p. 4451 - 4456 (1991)

The neutral pentane extract of the leaves and flower heads of Artemisia tridentata cana was found to contain two new naturally occurring chrysanthemyl derivatives 21a and 22a in addition to several previously characterized monoterpenes.The structures of these compounds have been established by spectral and chemical means including synthesis.In the process of establishing these structures it was found that lavandulyl skeletal artifacts were formed.The structures of these artifacts were also established by chemical and spectral means.
