Abstract
| - Dirhodium(II) salts efficiently catalyze the three-componentassembly reaction of an imine, diazoacetonitrile (DAN), andan activated alkynyl coupling partner to form substituted 1,2-diarylpyrroles in moderate to good yields. The transition-metal-catalyzed decomposition of the diazo compound in thepresence of the imine presumably generates a transientazomethine ylide that undergoes cycloaddition with dipolarophiles in a highly convergent manner.
