New access to oxazolopyridines via hydroxyamidine derivatives; application to quinolines

Several 2-aryl and 2-heteroaryloxazolo[4,5-b]pyridines were synthesised in high yields from zwitterion or hydroxyamidine derivatives by heating in dimethylacetamide. These intermediates were generated via hetarynic reaction with the complex base NaNH2-t-BuONa (5:2). The same reactions were possible with quinoline derivatives.
