Cs. Cho et al., Synthesis of quinolines by ruthenium-catalyzed heteroannulation of anilines with 3-amino-1-propanol, J HETERO CH, 36(5), 1999, pp. 1175-1178
Anilines react with 3-amino-1-propanol in dioxane in the presence of a cata
lytic amount of a ruthenium catalyst and tin(II) chloride dihydrate togethe
r with a hydrogen acceptor to afford the corresponding quinolines in modera
te yields.
