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