  Convergent Synthesis of the CDEF Ring Fragment of Yessotoxin via a-Cyano Ethers

  摘要：

  The synthesis of the CDEF ring fragment of yessotoxin, a marine ladder polyether, has been achieved. Union of three components, the C ring aldehyde, the F ring diol, and trimethylsilyl cyanide, was accomplished by treatment with Sc(OTf)(3) to afford the alpha-cyano ether both in stepwise and one-pot reactions. The DE ring system was constructed through a ring closing metathesis reaction and reductive etherification sequence.
