Synthesis of 2-Oxazolones and α-Aminoketones via Palladium-Catalyzed Reaction of β,β-Dibromoenamides
摘要:
beta,beta-Dibromoenamides show two different interesting reactivities based on the choice of R group under the reaction conditions. On the basis of mechanistic studies, both reactions proceed via an intermolecular Suzuki-Miyaura C-C coupling and an intramolecular C-O coupling.

The firstsyntheticroute to yndiamides, a novel class of double aza‐substituted alkyne, has been established by the copper(I)‐catalyzed cross‐coupling of 1,1‐dibromoenamides with nitrogen nucleophiles. The utility of these compounds is demonstrated in a range of transition‐metal‐catalyzed and acid‐catalyzed transformations to afford a wide variety of 1,2‐diamide functionalized products.
