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.
在回流的二甲苯或1,2-二氯苯中,意外地获得了N-酰基吲哚啉,产率良好,这由亚氟膦的连续环化反应实现。这种新方法为生物重要的吲哚啉提供了高效直接的合成途径,后者可以进一步氧化为吲哚和氧吲哚。
