Résumé
Dimethyl dimedone, a non chiral and cheap compound, has been converted to the optically active 1-(R)-cis- and 1-(R)-trans-chrysanthemic acids possessing high economic value. These processes involve as the key steps (i) a cyclopropanation reaction (ii) a Grob fragmentation and (iii) a lipase monitored hydrolysis of the prochiral diacetate.
