Cyclic 2-alkyl-1,3-alkanediones are ubiquitous structural motifs in many natural products of biological importance. Reported herein is an AlCl3·MeNO2-mediated Dieckmann cyclization reaction of general synthetic utility that enables direct access to complex 2-alkyl-1,3-dione building blocks from readily available dicarboxylic acid and acid chloride substrates. This new strategy enables direct synthetic

a 3-alkyl resorcinol derivative (3) precedes alkylation was applied in the synthesis of chiloglottone 1 (1dc), in 58% overall yield. Chiloglottone 1 is a member of a new class of natural products, representing a known sex pheromone of the thynnine wasp Neozeleboria cryptoides and pollinator attractant in the Australian sexually deceptive orchid genus Chiloglottis. The synthetic homologues were assessed
