Copper-Catalyzed Cascade Reactions of N-(2-Bromoallyl)amines with KHCO3 as the C1 Source: An Efficient Process for the Synthesis of Oxazolidin-2-ones.

A novel synthesis of oxazolidin-2-ones by carbamic acid formation and a subsequent copper-catalyzed intramolecular vinylation from N-(2-bromoallyl)amines and KHCO3 was developed. KHCO3 was used as a C1 source and base in this efficient and convenient cascade process.
