KEYWORDS An efficient method for synthesis of quinoxalines and substituted pyrido-pyrazines has been developed from different 1,2-dicarbonyl compounds and substituted 1,2-diamines using Indion 190 resin as a solid acid catalyst. Ambient reaction conditions, high product yield and reusability of the catalyst with minimal loading are the salient features of the present protocol.doi:10.5155/eurjchem.4.4.422-424.857 fatcat:ngia4v6uqjhxnktr54vsyu7wt4
