Abstract

A transition metal-free, base-mediated efficient synthesis of novel beta-carboline C1(3) tethered triazines has been accomplished by using beta-carboline alkaloid; Kumujian C as a template for reaction with readily available amidines. The strategy has been found compatible with diverse 1(3)-formyl beta-carbolines and amidines, providing access to wide variety of novel beta-carboline linked 1,3,5-triazines in good to excellent yields. The methodology is also amenable to gram scale synthesis of triazines. The presented methodology features sustainable reaction conditions, clean and simple methodology, low environmental impact, wide substrate scope and high atom economy with good to excellent yields. Moreover, the light emitting properties of these fluorescent beta-carboline linked triazine derivatives were investigated for the first time where quantum yield (phi(F)) up to 60% was obtained.
