Direct approach to indoles: The title reaction generates cyclohepta[b]indole derivatives in a single step at room temperature (see scheme). Exclusion of air or moisture is not required. DFT calculations support a stepwise cyclization event, and the versatility of the method is demonstrated by providing quick access to a library of cyclohepta[b]indole analogues.
吲哚的直接方法:标题反应在室温下仅一步即可生成环庚[ b ]吲哚衍生物(参见方案)。不需要排除空气或湿气。DFT计算支持逐步环化事件,并且该方法的多功能性通过提供对环庚[ b ]吲哚类似物库的快速访问而得到证明。
