• 2,4- vs 3,4-Disubsituted Pyrrole Synthesis Switched by Copper and Nickel Catalysts
  作者：Feng Chen、Tao Shen、Yuxin Cui、Ning Jiao

  A novel and efficient copper or nickel catalyzed highly selective denitrogenative annulation of vinyl azides with aryl acetaldehydes has been developed. 2,4- and 3,4-diaryl substituted pyrroles, which are difficult to synthesize by the reported methods, can be highly regioselectively prepared by this protocol simply switched by the selection of the transition metal catalysts. Compared with the reported acidic or basic conditions for polysubstituted pyrrole synthesis, the present reaction conditions are mild, neutral, and very simple without any additives.
• A Paal–Knorr Approach to 3,4-Diaryl-Substituted Pyrroles: Facile Synthesis of Lamellarins O and Q

  日期：——

  A very simple, yet efficient synthetic methodology, to obtain 3,4-diaryl-substituted pyrroles is described. The approach is based on the Knoevenagel condensation between arylacetonitriles and substituted aromatic aldehydes, followed by conjugate addition of cyanide to afford succinonitriles in excellent yields. The products thus obtained were subjected to DIBAL-H reduction, followed by cyclization under acidic conditions to produce the corresponding pyrroles in good overall yields. The utility of this protocol is exemplified by the synthesis of the marine alkaloids lamellarins O and Q.

  synthesising symmetrical and non-symmetrical 3,4-diaryl-substituted pyrroles is proposed, consisting of (i) the condensation reaction between phenylacetonitriles and aldehydes to give acrylonitriles, (ii) the conjugate addition of cyanide to afford succinonitriles, and (iii) reduction of the succinonitriles with DIBAL-H to provide the target pyrroles in good overall yields.
