new twist: A one‐pot nitrous acid free, diazonium‐free, and transition‐metal‐free variation of the Fischer indole synthesis has been developed. Condensation of quinone monoketals and aliphatic hydrazine hydrochlorides afforded indoles via intermediate alkylaryldiazenes. This method will complement the classical Fischer indole synthesis by providing indoles in two steps from widely available phenols
The development of aerobic oxidative C–H/N–H cross-coupling catalyzed by the first-row transition metals is attractive yet challenging. Here, the first iron-catalyzed intramolecular cross-dehydrogenative coupling for the synthesis of carbazoles and indoles using air as the oxidant is reported. The general and efficient protocol allows for C–Nbondformation under green conditions with excellent functional
Herein, a one-potsynthesis of 3-substituted indoles from 2-(2-nitro-1-phenylethyl)cyclohexanone derivatives catalyzed by Pd/C is reported. The starting materials can be easily prepared by the reaction of substituted ketones and nitroalkenes. The facile experimental procedure comprises the treatment of 2-(2-nitro-1-phenylethyl)cyclohexanone derivatives with H2 as a hydrogen donor in the presence of
