Lewis acid catalyzed synthetic approaches toward unsymmetrical diaryl- and triarylmethanes

Abstract

The research work carried out is primarily focused on the Lewis acid catalyzed 5-endo-dig cyclization and/or conjugate addition approaches for the synthesis of unsymmetrical diaryl- and triarylmethanes using 2-(2-enynyl)-pyridines or p-quinone methides (p-QMs) as synthetic precursors.
