The title compounds, namely 8,8'-bis-5,6,11,12-tetrahydrodibenzo[b,f][1,5]diazocines, have been synthesized in 36-81% yields through a one-pot reaction by treatment of N,N,N',N'-tetramethylbiphenyldiamine with the Vilsmeier's reagents derived from substituted N-methylformanilides and POCl 3 . This was another application of 't-amino effect' in the synthesis of eight-membered ring systems. These products
标题化合物,即 8,8'-bis-5,6,11,12-tetrahydrodibenzo[b,f][1,5]diazocines,通过一锅法反应合成,收率 36-81% N,N,N',N'-四甲基联苯二胺与 Vilsmeier 试剂衍生自取代的 N-甲基甲酰苯胺和 POCl 3 。这是“t-氨基效应”在八元环系统合成中的另一种应用。这些产品被设计为新型大环化合物的前体。
