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.
