Highly Fluorescent Pyrido[2,3-b]indolizine-10-Carbonitriles through Pseudo Three-Component Reactions of N-(Cyanomethyl)pyridinium Salts

An interaction of N-(cyanomethyl)pyridinium salts with vinamidinium perchlorates or enaminones proceeds as a pseudo-three component process and results in the formation of 3- or 2-substituted pyrido[2,3-b]indolizine-10-carbonitriles, respectively. Optical properties of these compounds have been evaluated, revealing effective green light emission with fluorescence quantum yields of up to 0.81. © 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
