Synthesis of fused systems in the isoquinoline series: Oxazolo- and pyrrolo[3,2-c]isoquinolines
In order to synthesize the pyrrolo[3,2-c]isoquinoline structure, three different routes starting from readily available isoquinolines were tried. The ring closure reaction of a malonic derivative of 4-amino-3-bromoisoquinoline led to an oxazolo[3,2-c]isoquinoline instead of the target molecule. This latter was obtained via Sonagashira coupling reaction followed by ring closure under basic conditions. A study of the lithiation of the N-sulfonated pyrrolo[3,2-c]isoquinoline was undertaken. After optimization of the lithiation conditions, various 2-substituted pyrrolo[3,2-c]isoquinolines were obtained and their oxidation reactions studied.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 27655-40-9, you can contact me at any time and look forward to more communication. Formula: C9H7NO3S.
