successive one-step formation of the 2-methyl-3-substituted indoles. Alternatively, the other type of 2-alkyl-3-substituted indoles could be synthesized in a one-pot operation, which consists of the Stille coupling reaction with the 1-(tributylstannyl)-1,3-disubstituted allenes, followed by TBAF treatment. This procedure could be applied to the synthesis of indomethacin.
[反应:见正文] N-酰基-2-碘苯胺与1-(三丁基锡烷基)-1-取代的烯的Stille偶联影响了2-甲基-3-取代的吲哚的连续一步形成。或者,另一种类型的2-烷基-3-取代的吲哚可以通过一锅操作合成,该操作由与1-(三丁基锡烷基)-1,3-二取代的烯基的斯蒂勒偶联反应,然后进行TBAF处理组成。该方法可用于吲哚美辛的合成。
