  Stereocontrolled synthesis of angularly fused tricyclic systems by tin-mediated radical cyclization

  摘要：

  Two efficient pathways for the stereocontrolled synthesis of functionalized, angularly fused tricyclic carbocycles from readily available 2-formylcycloalkanones are described. Tricyclo[7.4.0.0(4,9)]tridecane 13, tricyclo[7.5.0.0(4,9)]tetradecane 16, and tricyclo[7.3.0.0(4,9)]dodecanes 20 and 21 were synthesized by means of path A. Path B is highly convergent, is 95% stereoselective, and leads to a tricyclo-[7.4.0.0(4,9)]tridecane skeleton 29.
