Regioselectivity in isoquinolinealkaloidsynthesis is analyzed here. Our experiments have shown that substituents on the aromatic ring of the starting amine are determinant in isoquinolinesynthesis. The use of dicyclohexylcarbodiimide in activating carboxylic acids for electrophilic aromatic substitution reactions is presented for the first time.

The larvicidal potential of several dopamine 1-phenylisoquinoline derivatives against Culex quinquefasciatus third instar larvae was investigated in a rational search for insecticides. The results showed that these isoquinolines presented moderate larvicidal activity, that the presence of a substituent is needed on carbon 1 for such activity to be presented and that it may be possible to develop novel insecticidal compounds having potential use in controlling insects by appropriate structural modification of 1-phenylisoquinolines. This article presents a possible structure-larvicidal activity relationship for isoquinolinic compounds.
