Pyrethrolone synthesis

This reaction was used in a synthesis of pyrethrolone (1) from butadiene (scheme... [Pg.180]

Even from the modem point of view the natural pyrethrin I is, in certain respects, still a quite good insecticide. Therefore a simple synthesis for pyrethrolone 557 is a challenge for applied chemists. But so far those syntheses start from allethrolone, which has to be ozonized to an aldehyde 358 for elongation to the Z/E-mixture of the conjugated pentadienyl side chain [745, 746] Reaction scheme 241. This mixture was separated by chromatographic methods. Apparently, nature is still the better chemist in this case. [Pg.125]

The same method of diene formation was applied to the synthesis of pyrethrolone (Equation 13), an alcoholic component of naturally occuring pyrethroids [14]. [Pg.146]
