Si,O-Heterocyclics

Several approaches to what are formally Si-0 and O-Si-O heterocycles have been reported, although these reactions invariably involve the use of the Si-O bond only as a temporary tether. The coupling and RCM of dissymmetric alcohols was reported by Eustache and co-workers <01TL239> and this method was applied in the synthesis of attenol A <020L4105>. Denmark and Yang performed the RCM of Si-O tethered dienes in tandem with silicon-assisted cross-...
