Enantiopure polycycles by sequential cycloadditions

The enolsilyl ether 2, generated from butynone adduct 3, which is easily available from the enantiomerically pure cyclopentadiene 1, proved to be a general building block for polycyclic anellation products to cyclohexenone. After proper adjustment of functional groups in the cycloadducts by means of high pressure Diels-Alder cycloadditions, the thermal retro-process provided routes to various enantiopure alicyclic and heterocyclic target compounds in high yields.
