  配位体对 Pauson-Khand 环加成的影响：中间体的捕获

  摘要：

  Pauson-Khand 钴介导的环加成反应已成为一种重要的合成反应。一些修改增加了反应的效用，包括有报道称叔胺 N-氧化物大大加快了分子内和一些分子间反应中的环加成速率。迄今为止，除了完全鉴定六羰基炔配合物之外，还没有直接证据支持热或氧化胺促进反应的机械假设。虽然氧化胺促进的反应通常比类似的热反应大大加速，但在氧化胺的存在下，1,6-烯炔的环加成速率可能会因硫、氮或氧的存在而进一步提高同炔基或双炔基位置

  Diastereoselective cycloisomerizations of enediynes via palladium catalysis

  摘要：

  Considerations of atom economy drive a search for reactions that are simple additions which, performed intramolecularly, are cycloisomerizations. Exposure of acyclic enediynes to a catalyst generated by mixing a Pd(O) complex with acetic acid normally in the presence of a phosphine ligand creates [5.6.51 and [6.6.51 tricycles with extraordinary diastereoselectivity of remote stereogenic centers. Effects of substituents on the tethers as well as the olefinic and acetylenic bonds reveal a wide tolerance of functionality. While geminal substitution facilitates the cycloisomerization, it is not required. Allylic oxygen plays a role as a regioselectivity control element. Cycloisomerization dominates over allylic ionization in such cases by proper tuning of the ligand. The mechanism of this reaction appears to vary depending upon the structure of the substrate. In the normal cases, the process involves three stages, initiation, propagation, and termination. Chemoselective initiation at the acetylenic linkage closest to one of the chain's termini occurs by hydropalladation. Propagation entails intramolecular carbametalations. Termination by beta-hydrogen elimination generates a hexatriene that undergoes high rotoselectivity in its disrotatory cyclization to generate the final product. Blocking formation of the hexatriene shuts down reaction. With substrates bearing a gamma-siloxypropiolate as the acetylenic initiator, cycloisomerization forms a tricycle with different positions of the double bonds. In contrast' to the case of the other substrates, blocking formation of a hexatriene does not shut down cycloisomerization. Invoking a novel intramolecular Diels-Alder reaction of a dienylpalladium intermediate derived from the diyne moiety with the olefin, likely assisted by coordination to palladium, accounts for our observations. The ease of availability of the acyclic substrates because of the versatility of the acetylenes combined with the high chemo-, regio-, and diastereoselectivity makes this atom-economical reaction a very practical approach for the construction of polycycles.

  reaction, including reports that tertiary amine N-oxides greatly accelerate the rate of cycloaddition in both intra- and some intermolecular reactions. To date, there has been no direct evidence to support the mechanistic hypothese for either the thermal or amine oxide promoted reactions beyond complete identification of the hexacarbonyl alkyne complex. While the amine oxide promoted reaction is normally
