  名称：

  Synthesis of 2-[N-(9-phenylfluoren-9-yl)amino]-1-indanones by anionic cyclization of phenylalanine-derived oxazolidinones

  摘要：

  A novel preparation of N-(phenylfluorenyl)-2-amino-1-indanones is described. The key step is the cyclization of aryl-substituted o-bromophenylalanine-derived oxazolidinones with n-BuLi by halogen-metal exchange followed by in situ intramolecular acylation of the aryllithium intermediate. When this method was applied to an optically pure oxazolidinone derived from an amino acid, cyclization occurred with complete retention of the integrity of the chiral center.
