Anacyclus pyrethrum D.C. (Compositae) contains N-(2'-p-hydroxyphenylethyl) deca-, dodeca-, and tetradecatrans-2, trans-4-dienamide, a new series of tyramine amides corresponding to isobutylamides which this plant produces. The tyramides, and the corresponding isobutylamides, are synthesised stereospecifically by phosphonateanion synthesis. Anacycluspyrethrum is found to contain the lignan (+)-sesamin and attention is drawn to the cooccurrence of lipid (and other) amides with lignans in a number of plants from three families (Compositae, Piperaceae, and Rutaceae).
