Benzoquinoline amines – Key intermediates for the synthesis of angular and linear dinaphthonaphthyridines

A systematic study on the condensation reaction of 2,4-dichlorobenzo[h]quinoline and naphth-1-ylamine in the presence of CuI as catalyst to functionalised mono- and di-substituted (naphthalen-1-yl)benzo[h]quinoline amines was described. Subsequently these mono- and di-substituted amines on polyphosp...

Description
Summary:A systematic study on the condensation reaction of 2,4-dichlorobenzo[h]quinoline and naphth-1-ylamine in the presence of CuI as catalyst to functionalised mono- and di-substituted (naphthalen-1-yl)benzo[h]quinoline amines was described. Subsequently these mono- and di-substituted amines on polyphosphoric acid catalysed cyclisation reaction with aromatic/heteroaromatic carboxylic acids led to the construction of angular and linear aromatic/heteroaromatic substituted dinaphthonaphthyridines in good yields.
