One-pot and metal-free synthesis of atropisomeric carbazolyl-indoles by a facile [4 + 2]-benzannulation in ethanol and investigation of their photoluminescence property

Abstract

With green ethanol as the sole solvent, a novel metal- and oxidant-free one-pot [4+2]-benzannulation method has been developed, contributing to the synthesis of a series of atropisomeric carbazolyl-indoles in good...
