Abstract

Abstract From common ivy Hedera helix, subsp. helix and from Hedera helix, subsp. canariensis the highly unsaturated CI7-alcohols falcarinol (1) and the so far unknown didehydrofalcarinol (2) [(3R)-heptadeca-1,9(Z),11(Z),16-tetraene-4,6-diyne-3-ol] was isolated and its structures identified by mass spectrometry and NMR. The (R)-configuration of falcarinol and didehydrofalcarinol was determined after catalytic hydrogenation to 3-heptadecanol by enantioselective capillary gas chromatography. Falcarinol and didehydrofalcarinol effect sensibilization and allergic skin reactions in minute concentrations.
