Synthesis of ring-A-substituted tryptophan by a palladium-catalyzed heteroannulation reaction
Coupling of substituted 2-iodoanilines with Me (S)-2-[di(tert-butoxycarbonyl)amino]-5-oxopentanoate, derived from glutamic acid, in DMF in the presence of Pd(OAc)2 and DABCO provides substituted tryptophans in good to excellent yields. [on SciFinder (R)]
