Abstract
Chapter 1 : The first chapter describes the zinc-catalyzed or tin-catalyzed reaction with diverse ynamides and nitrosoarenes through aza-Nazarov cyclization, allowing the facile and efficient synthesis of various 2-aminopyrroles in moderate to good yields. This pyrrole fragment can be the precursor of several nature molecules. Chapter 2 : The second chapter describes concise TfOH-mediated [2 + 2 + 2] cycloaddition of ynamides with two discrete nitriles to synthesize seven pyrimidine-based emitters following by measurements of optical properties. These new derivatives show near-UV and blue fluorescent emissions (336 ~ 457 nm) with moderate quantum yields. One emitter (II-4g) was given an outstanding PL quantum yields (ηPL = 79%) with NUV emission which can be adjust and apply in UV-light OLED devices.
