Abstract

A group of imidazo [1, 2-a] quinoxalines have been synthesised from quinoxaline by condensation of an appropriate haloester or intramolecular cyclisation of a keto moiety on an intracyclic nitrogen atom. The reactivity of the heterocycle was explored through diverse reactions such as electrophilic substitution, lithiation and halogen–metal exchange to give access to a new series of derivatives. Confirmation of their structure was mainly performed ...
