Metal-catalyzed reaction of N-(2-indolyl)methyl, N-bis(trimethylsilyl)methyl diazoamides: an entry into the β-carboline ring system†
Abstract
The intramolecular metal-catalyzed reaction of N-(2-indolyl)methyl, N-bis(TMS)methyl diazoamides proceeds with high conformational control and chemoselectivity to give
