Chrysanthemic acid (I, R = H) constitutes an acidic component of the pyrethroid, 1 which is effective as an insecticide. Among its four optical isomers, the naturally occurring d-trans isomer has the highest activity.

Asymmetric induction was observed in the decomposition of diasoalkanes in the presence of certain chiral copper complexes. 1 We have applied this chiral carbenoid reaction to the synthesis of chrysanthemic acid\* (ea. 1). Systematic studies have been carried out to achieve an optical yield of 60-70$

## Abstract A facile asymmetric synthesis of [C‐1‐^3^H]‐labelled (+)‐trans[1R,3R]‐chrysanthemic acid, required for biosynthetic studies is described. The tritium labelled acid is prepared from the corresponding (−)‐cis[1S,3R]‐ester by selective epimerisation of the C‐1 centre in the latter, in the
