Abstract
Monocyclic silyl enol ethers tethered to an olefinic or a silylacetylenic side chain are irradiated in the presence of the electron transfer sensitizer 9,10-dicyanoanthracene (DCA). Cyclization of the initially formed silyloxy radical cations efficiently provides bicyclic and tricyclic ketones with definite stereochemistry. The endo/exo regiochemistry of the cyclization step can be controlled by addition of alcohol involving a radical cationic and a radical reaction pathway. Copyright (C) 1996 Elsevier Science Ltd
