The reaction of 2-iodo-2,4-dimethylaniline with 3,4-dibromo-4- methyltetrahydro-2H-pyran, followed by treatment with acetyl bromide or 4-nitrobenzoyl chloride, gave syn- and anti-atropisomers of N-(2-iodo-4,6- dimethylphenyl)-N-(4-methyl-3,6-dihydro-2H-py

A practical diastereoselective method for the synthesis of benzoannelated tri- and tetracyclic bridged sultams has been developed. The synthetic route employs widely available, substituted -iodoanilines and is based on intramolecular Michael addition followed by cycloalkylation with dihaloalkanes, or vice versa. The target compounds were isolated in good yields and the diastereoselectivity of the reaction could be easily controlled by the order of Michael addition and cycloalkylation steps.

The invention belongs to the technical field of organic chemistry and particularly relates to a method for preparing o-haloaromaticamine from C-H-based activated arylamines. The method comprises the following steps: taking anhydrous copper acetate as a reaction catalyst and hydrogen peroxide as an oxidizing agent, adding aniline compounds and potassium bromide or potassium iodide into water for reaction at room temperature for 2 h, extracting with ethyl acetate and concentrating under reduced pressure, so as to obtain a corresponding arylamine halogenated compound crude product; and performing column chromatographic isolation and purification to obtain a corresponding purified product. The method has the characteristics that the operation is simple, reaction conditions are mild, the reaction time is short, and the method is environment-friendly.
