  摘要：

  Abstractmagnified imageBenzo‐fused heterocyclic and carbocyclic systems have been synthesized by intramolecular SNAr and tandem SN2‐SNAr reactions. Treatment of 3‐(2‐fluoro‐5‐nitrophenyl)‐1‐propanol with sodium hydride in N,N‐dimethylformamide gave 6‐nitrochroman in 80% yield by an intramolecular SNAr reaction. Treatment of 2‐(3‐bromopropyl)‐1‐fluoro‐4‐nitrobenzene with benzylamine in N,N‐dimethylformamide gave 1‐benzyl‐6‐nitrotetrahydroquinoline in 98% yield by a tandem SN2‐SNAr reaction. Finally, in a similar process, reaction of this same bromide with dimethyl malonate under basic conditions gave 1,1‐bis(methoxycarbonyl)‐6‐nitro‐1,2,3,4‐tetrahydronaphthalene in 80% yield. Further studies exploring ring size effects are also presented.
