Synthesis of murrayaquinone A and analogues via ring-closing C–H arylation
摘要:
A compact synthesis of Murrayaquinone A is reported, based on sequential Buchwald-Hartwig amination/annulative C-H activation followed by oxidation of the intermediate carbazole. The methodology can be readily extended to other analogues with electron-rich quinone rings. (C) 2013 Elsevier Ltd. All rights reserved.
