The insecticidal activity found for rocaglamide and its congeners, prompted us to establish a short and efficient synthesis of the natural product and some synthetic 'halo-aryl' analogues. Pd-catalysed cross-coupling reactions of the bromo analogue were then explored in order to gain a suitable access to a broad range of unnatural analogues. The key step of our approach is a keto-aldehyde acyloin ring-closure followed by a Stiles carboxylation.

Two approaches to the rocaglamide tricyclic skeleton are described.The first, which employs an unusual dithianyl anion to carbonyl addition reaction, provides access to α-phenyl rocaglamide analogues.The second route involves an intramolecular keto aldehyde pinacolic coupling in the key step and can be used for the preparation of a whole range of rocaglamide analogues possessing both α- and β-phenyl substituents.A total synthesis of rocaglamide, in racemic form, is described using this second approach.The synthetic route commences with phloroglucinol, an inexpensive and readily-available starting material, and takes only 8/9 steps giving an overall yield > 6percent.The synthesis of 1-epi-rocaglamide 29b is also described.
