WebChrysanthemic acid occurs as a mixture of esters in flowers of the chrysanthemum (pyrethrum) family. Reduction of chrysanthemic acid to its alcohol, followed by conversion of the alcohol to its tosylate, gives chrysanthemyl tosylate. Solvolysis of the tosylate gives a mixture of artemesia and yomogi alcohols. WebThe pyrethrum plant, Tanacetum cinerariifolium (Asteraceae) synthesizes a class of compounds called pyrethrins that have strong insecticidal properties but are safe to humans. Class I pyrethrins are esters of the monoterpenoid trans-chrysanthemic acid with one of three jasmonic-acid derived alcohols …
