  Synthesis of Cyclic cis-Enediynes from Manganese Carbyne Complexes and α,ω-Diynes

  摘要：

  Cyclic cis-enediynes are readily prepared by a two-step one-pot procedure. The first step is the copper-catalyzed addition of alpha,omega-diynes to manganese carbyne complexes to give intermediate bis(alkynylcarbene) complexes that rearrange to enediyne complexes below room temperature. In the second step, the free enediyne is released from manganese by photolysis, copper-catalyzed air oxidation, or stoichiometric Cu(II) oxidation. These new procedures have been applied to a variety of five-, six-, and seven-membered-ring cyclic enediynes containing a range of ether, ester, and ketone functional groups.

• Manganese Trifluoroacetoxycarbene Complexes Are Convenient Intermediates in the Synthesis of Cyclic Enediynes

  Trifluoroacetoxycarbene complexes generated from reaction of stable manganese acyl complexes with trifluoroacetic anhydride are convenient alternatives to thermally sensitive manganese carbyne complexes in reactions with diynes that lead eventually to free cyclic enediynes. In situ reaction of these trifluoroacetoxycarbene complexes with alkynyl copper intermediates generated from diynes, CuBr, and NEt(i-Pr)(2) led to the isolation of cyclic enediynes via intermediate linked alkynylcarbene complexes and manganese enediyne complexes.
