Both racemic [2-14C] juvenile hormone 111 (JH 111; methyl-l0,11-epoxy-3,7,11t rimethyl-2(E) , 6 ( E ) [2-14C]dodecadienoate) and its 2-(2) isomer were synthesised on a 1 millimolar scale by forming the 9,lO epoxide of geranyl acetone and reacting this with the anion of trimethylphosphon0-[2-~~C]acet
The cyclic analogue rac-14b of JH-I11 and its 22 isomer roc-14a were obtained by a multi-step synthesis starting from rac-a-terpineol. The Wadsworth-Emmons reaction was applied to the formation of the carbon chain and to the introduction of the ester function (esters 8a, b and 13% b). Morphogenetic
