A stereospecific route to cis-2,2-dimethyl-3-alkenyl-cyclopropanecarboxylic Acids is illustrated by a total synthesis of (±)-cis-Chrysanthemic Acid (11). The key step consists of an alicyclic Claisenrearrangement of O-silyl enolates derived from appropriately substituted (Z)-4-hexen-6-olides [e.g.(9)].
