## 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 (βˆ’)‐cis[1S,3R]‐ester by selective epimerisation of the C‐1 centre in the latter, in the
