The modification of strong Csp3?H bonds via iron carbene intermediates under mild reaction conditions has been an important challenge with attractive prospective in organic synthesis. In this work, we show the efficient combination of an electrophilic iron catalyst with a lithium Lewis acid for the functionalization of strong Csp3?H bonds of cyclic and linear alkanes by the activation of commercially available ethyl diazoacetate (EDA). The reaction proceeds with good yields, under mild reaction conditions (40 °C) and large excess of substrate is not needed. In addition, excellent activity is observed in the cyclopropanation of challenging aliphatic olefins. (Figure presented.).

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
