number of natural products that display important biological activity. A flexible, stereoselectiveapproach to the framework has been developed that features highly diastereoselective, SmI2-mediated cyclisations. The strategy has been exploited in the first synthesis of the proposedstructure of faurinone and an approach to the skeleton of the antibacterial natural product, pleuromutilin.
The intramolecular addition of allylsilanes to conjugateddienones shows a divergence of regioselectivity as a function of reagent and substrate structure. The creation of 5-5, 6-5, 5-7, and 6-7 bicyclic ring systems is reported.
