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.

N-Formyl, -acetyl, and -benzoyl groups can be removed from secondary amides with amines under mild conditions after t-butoxycarbonylation, giving acid-labile t-butylcarbamates.
