Insect Growth Regulators. XVI Syntheses of Juvenoids with the 3,3-Dimethylcyclohexane System.

Article abstract of DOI:10.1007/BF00798283

New cyclic juvenoids containing the 3,3-dimethylcyclohexane (esters 16, 18, 22, 26, and ehters 28a,b) or the 5,5-dimethyl-2-cyclohexene system (esters 15, 17, 21, 25, and ehters 27a,b) have been obtained by a several-step synthesis starting from dimedone (1).The compounds obtained exhibited morphogenetic activity against larvae of Dysdercus cingulatus and they were inactive on pupae of Tenebrio molitor.Keywords: Claisen rearrangement; gem-Dimethylcyclohexane derivatives; Juvenoids
