  Cyclobutene Ring-Opening of Bicyclo[4.2.0]octa-1,6-dienes: Access to CF₃-Substituted 5,6,7,8-Tetrahydro-1,7-naphthyridines

  摘要：

  An efficient method for the synthesis of novel CF3-substituted tetrahydro-1,7-naphthyridines including cyclic alpha-amino acid derivatives has been developed. The method is based on unusual cyclobutene ring-opening of bicyclo[4.2.0]octa-1,6-dienes with pyrrolidine to afford the corresponding 1,5-diketones followed by their heterocyclization. A convenient one-pot procedure has been also elaborated starting from readily available trifluoromethylated 1,6-allenynes.
