Unexpected synthesis of N-Acyl indolines via a consecutive cyclization of iminophosphorane

Li, Wen-Jing,Zhao, Fen-Fen,Ding, Ming-Wu

, p. 265 - 267 (2011)

N-Acyl indolines were obtained unexpectedly from a consecutive cyclization of iminophosphorane in refluxing xylene or 1,2-dichlorobenzene in good yields. This new approach provides an efficient and direct access to the biologically important indolines which are further oxidizable to indoles and oxindoles. Georg Thieme Verlag Stuttgart.
