Abstract Nitroarenes are reductively cyclized with 3-amino-1-propanols in dioxane/H 2 O in the presence of a ruthenium catalyst and tin (II) chloride dihydrate together with isopropanol to afford the corresponding quinolines. A reaction pathway involving initial reduction of nitroarenes to anilines, propanol group transfer from 3-amino-1-propanols to anilines, N- alkylation of anilines by 3-anilino-1-propanols and heteroannulation of 1, 3- ...
