Some electrophilic reactivity studies of di-(2-indolyl)dibenzofurans and di-(2-indolyl)carbazoles
摘要:
3,6-Bis-(2-indolyl)dibenzofurans 1,2, and carbazoles 3-6 underwent a range of electrophilic substitution reactions to produce formyl indoles 7-12, biindolyls 24-28 and 33-34, glyoxylamides 40-42, and amides 48. (C) 2014 Elsevier Ltd. All rights reserved.
Synthesis of macrocyclic systems derived from di-(2-indolyl)heteroarenes
摘要:
A number of new 3,6-di-(2-indolyl)-dibenzofuran and carbazole derivatives have been prepared from dibenzofuran and carbazole linkers via the Fischer indole synthesis. The bis-indoles were successfully formylated at C3 and the resulting dicarbaldehydes were combined with diamines to generate indole based imine macrocyclic systems. (C) 2012 Elsevier Ltd.
