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.
