  Atom-Economical Chemoselective Synthesis of 1,4-Diynes and Polysubstituted Furans/Pyrroles from Propargyl Alcohols and Terminal Alkynes

  摘要：

  Under different conditions, the reaction of propargyl alcohols and terminal alkynes leads to the selective formation of 1,4-diynes and polysubstituted furans/pyrroles. Water is the only byproduct in the selective synthesis of 1,4-diynes and pyrroles, and the strategy for the furan synthesis is of 100% atom economy.

  directly from aromatic aldehydes is described. The starting aldehyde behaves as a traceless functionality in the formation of multiple carbon–carbon bonds through consecutive carbon–heteroatom bond activations. The sequential addition of a metal acetylide and a second carbon nucleophile to the dielectrophilic aldehyde enables the construction of symmetrical and unsymmetrical 1,4-diynes in good yields

  描述了直接由芳族醛进行钛碳烯催化的全碳取代的叔中心的结构。起始醛通过连续的碳-杂原子键激活，在形成多个碳-碳键时表现为无痕的功能。将金属乙炔化物和第二个碳亲核试剂顺序地添加到该二亲电子醛中使得能够以良好的产率构建对称和不对称的1，4-二炔。
