Copper-mediated selective aerobic oxidative C3-cyanation of indoles with DMF
摘要:
Under an oxygen atmosphere, the copper-mediated direct C3-cyanation of indole C-H bonds, using cheap and safe DMF as a CN source, took place selectively to produce the corresponding C3-cyanoindoles in good yields. A possible mechanism for this selective cyanation was proposed. (C) 2015 Elsevier Ltd. All rights reserved.
