selective C–N coupling reaction of diaryliodoniumsalts and dinucleophiles under mild conditions was realized. Diaryliodoniumsalts prefer to react with dinucleophiles at the site of stronger alkalic amino groups. Thus, a general aliphatic amino-selective N-arylation of α-amino amides was disclosed. Additionally, copper-catalyzed N-arylation of diaryliodoniumsalts afforded the same products as obtained
2-Azadienes 1 bearing a trialkylsilyloxy group on position 3 can be regarded as carboxylic acid synthons. Their cycloadditions with several classes of nitroso compounds have been studied in details as well as the transformation of the adducts into α-amino acids. This study showed that arylnitroso compounds such as nitrosobenzene reacted with 2-azadienes to give adducts that are potential precursors
Give me an N: The catalytic amination of α‐hydroxy amides with a variety of amines, including anilines, primary and secondary aliphatic amines, and ammonia, yields a wide range of α‐amino amides (see scheme). This atom‐efficient amination protocol proceeds efficiently in the presence of a commercially available [Ru3(CO)12]/DCPE catalyst system.
