Pd(II)-Catalyzed Direct Sulfonylation of Benzylamines Using Sodium Sulfinates
摘要:
A Pd(II)-catalyzed direct sulfonylation of benzylamines with sodium sulfinates using a removable bidentate directing group is illustrated. The transformation is highly regioselective and tolerates wide functional groups. The mechanistic study reveals that radical species are involved in this reaction. This method delivers a direct synthetic strategy to obtain highly functionalized sulfonylated benzylamines.

The synthesis of a series of 2-, 3-, and 4-substituted benzylamine derivatives is described. These compounds were studied for their effect on experimental cardiac arrhythmias. Many of the derivatives, but in particular 2-(p-methoxyphenylethynyl)benzylamine (3d), alpha,alpha-dimethyl-4y(phenylethynyl)benzylamine (7a), and alpha,alpha-dimethyl-4-phenethylbenzylamine (12g), showed good antiarrhythmic activity.
