• Visible-Light-Promoted Redox Neutral C–H Amidation of Heteroarenes with Hydroxylamine Derivatives
  作者：Qixue Qin、Shouyun Yu

  日期：2014.7.3

  redox neutral direct C–H amidation of heteroarenes has been achieved. Hydroxylamine derivatives, which are easily accessed, have been employed as tunable nitrogen sources. These reactions were enabled by a visible-light-promoted single-electron transfer pathway without a directing group. A variety of heteroarenes, such as indoles, pyrroles, and furans, could go through this amidation with high yields (up

  Reported herein is an effective strategy for oxidative cross-coupling of indoles with various aldehydes. The strategy is based on a two-step transformation via a well-known Mannich-type reaction and a C–N bond cleavage for carbonyl introduction. The key step—the C–N bond cleavage of the Mannich product—was enabled by electrochemistry. This strategy (with over 40 examples) ensures excellent functional-group

  An efficient indole-to-carbazole strategy has been developed under metal-free conditions. This carbazole formation was highly promoted by NH4I with high regioselectivity through formal [2 + 2 + 2] annulation of indoles, ketones, and nitroolefins. It thus conveniently enabled the assembly of a large number of diversified carbazole products with good tolerance of a broad range of functional groups.
