Synthesis of 7,12-dihydro-12-phenyl-5H-6,12-methanodibenz[c,f]azocines via N,N-dibenzylphenacylamines

, 1998
N,N-Dibenzylphenacylamines (1) were prepared in high yields by a one-pot reaction and cyclized at room temperature to give 7,12-dihydro-l2-phenyl-5H-6,1 2-methanodibenz[c,f]azocines in high yields. 95% H2SO4 or 70% HClO4 was used as cycIization catalysts.

Iodine(III)-Catalyzed Oxidative Cyclization of Aryl Amines to Construct Benzimidazoles [PDF]

An I(III)-catalyzed oxidative cyclization reaction using Selectfluor as the oxidant was developed that converts ortho-substituted anilines to benzimidazoles is reported. The mild reaction requires as little as 0.5 mol % of iodobenzene tolerating electron-
