G. Rucker et al., PEROXIDES AS CONSTITUENTS OF PLANTS .15. IRREGULAR MONOTERPENE PEROXIDES FROM ACHILLEA-FILIPENDULINA LAM, Archiv der pharmazie, 327(5), 1994, pp. 277-282
From Achillea filipendulina LAM. (Asteraceae) two hitherto unknown dia
stereomeric, irregular acyclic monoterpene peroxides 5, 6 of santolina
triene type have been isolated (4alpha- and 4beta-peroxyachipendole).
The constitution of 5 was confirmed by X-ray analysis. Reduction of 5
and 6 results in the formation of the alcohols 8 and 9, respectively.
Constitutions of 8 and 9, reported in lit., have to be corrected. In
addition, ascaridole (1), trans-pinocarveylhydroperoxide (2) and isoly
ratylhydroperoxide A (3) and B (4) have been found.
