expedient route to densely substituted 7-hydroxyindoles. Intrinsic to the methodology, the resulting substituents are disposed in a fully regiocontrolled manner. The methodology is applicable to the synthesis of 7-hydroxybenzofurans. None of the indoles/benzofurans or pyrrole synthons synthesized in this study have hitherto been reported.
适当的 2,3-二取代
吡咯与迈克尔受体的阴离子环化提供了一种获得密集取代的
7-羟基吲哚的便利途径。对于该方法而言,所得到的取代基以完全区域控制的方式布置。该方法适用于
7-羟基苯并呋喃的合成。迄今为止,尚未报道本研究中合成的
