The intramolecular Diels-Alder reaction is widely recognized as a powerful and versatile method for the assembly of complex bicyclic structures in synthetic organic chemistry and has been utilized as a key step in the total syntheses of a number of interesting biologically active natural products. We have studied the use of siloxacyclopentene constrained trienes as a method to control diastereofacial selectivity in the intramolecular Diels-Alder reaction. The siloxacyclopentene constraints could be formed under mild conditions and attached to either the diene or dienophile units of a variety of trienes. These constrained trienes underwent intramolecular Diels-Alder reactions to give cycloadducts with the oxygen contained in the siloxacyclopentene exclusively in an anti-configuration relative to the ring fusion proton. Suitably chosen dienophile activating groups and optimized conditions for cyclization allowed for high levels of selectivity for either cis - or trans -fused cycloadducts in the case of siloxacyclopentenes contained within the diene, while siloxacyclopentenes constraints attached at the dienophile gave exclusively the trans-fused cycloadducts. A siloxacyclopentene constrained tetraene was then utilized in a concise, stereoselective synthesis of the decahydrofluorene core common to the hirsutellones. Synthetic efforts targeting the completion of the hirsutellones via a common biosynthetic intermediate were pursued utilizing a macrobenzannulation strategy. This strategy was abandoned due to inability to prepare a suitable benzannulation precursor. Later a strategy of first forming a five membered ring containing analogue was also pursued, but failed due to an inability to convert a suitable ester to the corresponding furan or thiophene.
