The intramolecular metal-catalyzed reaction of N-(2-indolyl)methyl, N-bis(TMS)methyl diazoamides proceeds with high conformational control and chemoselectivity to give cyclopropyl derivatives, which rearrange to beta-carboline products.

The Rh(II)- and Cu(II)-catalyzed reactions of N-bis(trimethylsilyl)methyl, N-(2-indolyl)methyl α-diazoamides are investigated to delineate how conformational, steric and electronic factors influence the site- and chemoselectivity of the metallocarbenoid reaction. The N-bis(trimethylsilyl)methyl (N-BTMSM) group is found to be essential in promoting the metallocarbenoid reaction at the N-(2-indolyl)methyl
