Biologically important, less-explored natural products of sexuallydeceptivechiloglottones, antimicrobialdialkylresorcinols, and their many analogues were synthesized in very good yields in a sequential two-pot manner by using an “organocatalyticreductivecouplingreaction” as the key step.

Chiloglottone, a wasp pheromone and attractant of sexually deceptive Chiloglottis orchids, and several structural analogs were synthesized. The synthetic approach is facile, high yielding and versatile, enabling rapid divergence to generate dialkylated analogs of chiloglottone. The key transformation was an organocadmium-mediated desymmetrization of glutaric anhydride derivatives. This library of synthetic 2,5-dialkylated 1,3-cyclohexanediones may assist in future identification of natural products in further species. (C) 2008 Elsevier Ltd. All rights reserved.
