Reactions of Alkylation of Biologically Interesting Triazolo[4,5-g]quinolines and Triazolo[4,5-g]quinoline-1-oxides with Electrophilic Reagents
摘要:
With the aim to improve the biological activities discovered for compounds containing the triazolo[4,5-g]quinoline nucleus, we describe the chemical behaviour of 4-chlorotriazolo[4,5-g]quinolines (1a,b) and some its triazolo-N(1)-oxide derivatives (1c-e and II) with electrophilic reagents in order to optimize the synthetic pathways for obtaining both mixtures of N(1,2,3)-alkyl isomers and selectively N(1)-O-alkyl derivatives.
