  摘要：

  3-(2-Bromoethyltosylamino)quinoline 1-oxide (4) reacted with TsCl-NH4OH and TsCl-K2CO3 to afford the 2-aminoquinoline (5) and the 2-quinolinone (8). Cyclization of 5 and 8 under basic conditions gave the piperazino-quinoline (6) and the morpholino-quinoline (9). Similar reactions of 3-(2-bromoethoxy)quinoline 1-oxide (13) in the presence of TsCl gave also the 2-aminoquinoline (14) and the 2-hydroxyquinoline (16), but accompanied with fair amounts of by-products (15 and, 15 and 17). Cyclization of 14 and 16 gave the morpholino-quinoline (18) and the 1,4-dioxano-quinoline (19) in somewhat lower yields.
