The reaction of 2-trimethylsilylmethylanilides and esters in basic medium provides a new general method for the synthesis of indoles. The advantages of this method are the mild reaction conditions (-10-0°C), the ready availability of the starting materials and the use of a non-nucleophilic base (lithium 2,2,6,6-tetramethylpiperidide) to promote cyclisation.
2-三甲基甲硅烷基甲基苯胺与酯在碱性介质中的反应为吲哚的合成提供了一种新的通用方法。该方法的优点是反应条件温和(-10-0°C),易于获得的起始原料以及使用非亲核碱(2,2,6,6-四甲基哌啶锂)促进环化。
