Hintz, Sandra published the artcileRegio- and stereoselective cyclization reactions of unsaturated silyl enol ethers by photoinduced electron transfer. Mechanistic aspects and synthetic approach, Product Details of C7H13BrSi, the publication is European Journal of Organic Chemistry (1998), 1583-1596, database is CAplus.
Oxidative photoinduced electron transfer (PET) reactions were performed with various silyl enol ethers and silyloxy-2H-chromones bearing an olefinic or silylacetylenic side-chain. The reactions result in regioselective ring-closure with the formation of bi- to tetracyclic ring systems with a well-defined ring juncture, e.g. perhydrophenanthrenones or benzo-annelated xanthenones. Our investigations have focussed on the optimization of this cyclization method with regard to irradiation time and product yield. The irradiation times could be reduced by using the cosensitized PET method. Modifying the substrate at the silyl group led to enhanced yields. In addition, it was found that solvent and pressure dependences are important tools, allowing control of the regiochem. Both the synthesis of 6-endo products by radical cationic reaction pathways as well as 5-exo ring-closure by radical intermediates was achieved. Mechanistic details, including findings from deuterium labeling experiments, are discussed.
