Synthesis of Free NH 2-(Aminomethyl)indoles through Copper-Catalyzed Reaction of 3-(ortho-Trifluoroacetamidophenyl)-1-propargylic Alcohols with Amines and Palladium/Copper- Cocatalyzed Domino Three-Component Sonogashira Cross-Coupling/Cyclization/Substitu
Free NH 2‐(aminomethyl)indoles have been prepared via copper‐catalyzed cyclization of 3‐(ortho‐trifluoroacetamidophenyl)‐1‐propargylic alcohols in the presence of primary or secondary amines. The synthesis has been developed into a simple and very efficient domino three‐component Sonogashira cross‐coupling/cyclization/substitution process that, omitting the isolation of 3‐(ortho‐trifluoroacetamido

Abstract Amides 1a–f reacted with phosphorane 3 at room temperature giving a mixture of enamine 4a–f and imine 6a–f tautomers in excellent yields. These tautomers were formed in competing reaction pathways. Silica gel promoted the conversion of 4d into 6d. Amides 1d and 1f reacted with the methyl analogue of phosphorane 3 giving tautomers 11a,b/12a,b. The β-amino acid derivatives, 13a,b, were formed from
