Journal of Chemical Research-s | 2005

Synthesis of some novel azido- and tetrazoloquinoline-3-carbonitriles and their conversion into 2,4-diaminoquinoline-3-carbonitriles

Ramadan Ahmed Mekheimer; G. E. H. Elgemeie; Thomas Kappe

Quinoline-3-carbonitriles carrying amino groups at the 2- and/or 4-position have been prepared via the corresponding azido- or tetrazolo-quinolines, through the intermediacy of phosphazenes.
