The present invention provides a novel (1,3-butadien-2-yl)methylamine derivative and a preparation method thereof. The (1,3-butadien-2-yl)methylamine derivative having the 1,3-diene substituent at the alpha-position is an useful precursor in preparing various amine compounds having biochemical activities.

Dirhodium(II) salts efficiently catalyze the three-component assembly reaction of an imine, diazoacetonitrile (DAN), and an activated alkynyl coupling partner to form substituted 1,2-diarylpyrroles in moderate to good yields. The transition-metal-catalyzed decomposition of the diazocompound in the presence of the imine presumably generates a transient azomethine ylide that undergoes cycloaddition
