  [3 + 4] and [3 + 5] Annulation Reactions of .alpha.-(Phenylthio)Dicarbonyl Electrophiles with Bis(trimethylsilyl) Enol Ethers: Synthesis of Highly Functionalized Medium Ring Carbocycles

  摘要：

  The [3 + 4] and [3 + 5] annulations of bis(trimethylsilyl) enol ethers with 1,4- and 1,5-dicarbonyl electrophiles bearing alpha-phenylthio substituents leads to the formation of bicyclic [3.2.1] and [3.3.1] ethers with good regiochemical and stereochemical control, Subsequent oxidation of the phenylthio moiety followed by reduction with SmI2 constitutes a high-yielding and regioselective process for cleavage of the bridging ether linkage. The overall strategy provides a synthetic pathway for the synthesis of highly functionalized medium ring carbocycles.

  The synthesis of cyclic bis(trimethylsilyl) enol ethers from cycloalkanone carboxylates is described. The [3 + 4] and [3 + 5] annulation reactions of these bis(dinucleophilic), synthons with various 1,4- and 1,5-dicarbonyl electrophiles leads to the formation of tricyclic keto ethers with good regio- and stereochemical control. An interesting trans intrabridgehead stereochemistry is observed when using bis(trimethylsilyl) enol ethers derived from nine- to 12-membered ring beta-keto esters.
