Asymmetric carbons are named as carbon 1, carbon … 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.
