Recently I am researching about VITRO ANTITUMOR-ACTIVITY; BIOLOGICAL EVALUATION; QUINOXALINE DERIVATIVES; FACILE SYNTHESIS; AGENTS; CONDENSATION; HETEROCYCLES; FLUORESCENCE; QUINAZOLINE; SENSITIZERS, Saw an article supported by the SERBDepartment of Science & Technology (India)Science Engineering Research Board (SERB), India [PDF/2016/001813]. Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Das, S; Maity, S; Ghosh, P; Paul, BK; Dutta, A. The CAS is 150-19-6. Through research, I have a further understanding and discovery of m-Methoxyphenol. Category: indole-building-block
Synthesis of fluorescent molecules has drawn considerable attention due to their potential applications in life and material sciences. Here we report a metal-free approach to a new class of fluorophore, namely, 6-(2-hydroxyarypisoindolo[2,1-a]quinoxalin-11(5H)-ones exploiting ninhydrin ring system via base promoted tandem cyclization. The readily obtainable phenolic adducts of ninhydrin undergoes smooth reaction with o-phenylenediamine in refluxing ethylene glycol/Et3N via breaking of C-C bond, N-insertion, followed by heterocyclization to furnish the fully unsaturated isoindoloquinoxaline framework. Structures of the products are in good agreement with their IR, 1HNMR, (CNMR)-C-13, and mass spectral data. The photophysical properties of the synthesized compounds were studied by UV-vis absorption and fluorescence spectroscopic techniques under ambient conditions, and the results reveal an interesting property of large Stokes shift.
