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.

A novel copper-catalyzed cascade synthesis of thiazolidine-2-thiones from N-(2-bromoallyl) amines and carbon disulfide has been developed. The procedure combines carbamodithioic acid formation and copper-catalyzed intramolecular S-vinylation in one sequence. By elevating the temperature, the one-pot reaction efficiently affords thiazole-2(3H)-thiones in moderate to good yields.

N-Phenyl or N-benzoyl 2-halogenoallylamines (5) or (10) react successively with phenyl-lithium and lithium naphthalenide at –78 °C to give the intermediates (4) or (11), which on reaction with electrophiles (water, deuterium oxide, dimethyl disulphide, aldehydes, ketones, or allyl bromide) yield functionalized allyl amines (6) and (12). The corresponding N-alkyl derivatives (9) afford prop-2-ynylamines
