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.

The amination of 2-chloroanilines with aryl bromides and subsequent intramolecular direct arylation can be exploited in the synthesis of a range of fluorinated carbazoles, where the fluorine substituent can be introduced via the aniline, the aryl bromide or both substrates. Depending on substitution patterns, the two steps can either be performed in tandem in one-pot under microwave heating conditions
