The cyclic analogue rac ‐ 14b of JH‐III and its 2 Z isomer rac ‐ 14a were obtained by a multi‐step synthesis starting from rac ‐α‐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 13a, b ). Morphogenetic activities of the cyclic juvenoids were compared with those observed for their acyclic analogues.
