Abstract :
Hemisynthesis of methyl pyrethroates from γ-alkoxy-alkylidene malonates and isopropylidenediphenylsulfurane and isopropylidenetriphenylphosphorane is disclosed. It takes advantage of the high degree of stereocontrol observed in the cyclopropanation of γ-alkoxy-alkylidene malonates by the above mentioned ylides.
