作为相应的磺胺或氨基甲酸酯保护的2-卤苯胺,可以通过与1-炔和5-末端碘环的顺序Sonogashira偶联,非常有效地转化为3-碘吲哚。Azaindoles也可以用这种方法得到。(C) 2003 Elsevier Ltd.版权所有。
2-Halo-anilines, protected as the corresponding sulfonamides or carbamates, can be converted very efficiently into 3-iodoindoles by sequential Sonogashira coupling with a 1-alkyne and 5-endo-dig iodocyclisation. Azaindoles can also be obtained using this methodology. (C) 2003 Elsevier Ltd. All rights reserved.
