Abstract

4-Oxo-6,11-dihydro-4H-thieno[3′,2′:5,6]pyrimido[1,2-b]isoquinolines have been synthesized by the reaction of o-bromo-methylphenylacetonitrile with esters of substituted 2-aminothiophene-3-carboxylic acids. They were characterized as the hydrobromides and as the fee bases. The tautonterism of the bases in DMSO solution is discussed.
