Radiolabelled juvenile hormone I (3) was prepared in an optically pure form by an enzymatic method using the capacity of accessory sex gland homogenates from maleHyalophora cecropia to transfer the methyl group of S-adenosyl-L-methionine to the carboxylic acid function of the (10R, 11S)-enantiomer of racemic presursor2; the specific activity of3 is higher than 53 Ci/mmole (1.96 TBq/mmole).
