A synthesis of an advanced intermediate towards the racemic form of the antiviral agent virantmycin has been developed featuring an intramolecular aza-xylylene Diels–Alder reaction. The required arylthiocarbamate has been constructed using an efficient oxidative cyclization strategy. A novel synthetic approach to chlorine-substituted allylic alcohols using an unprecedented palladium-catalyzed cross-coupling

oxazolidinethiones from amines and carbondisulfide has been achieved in DMSO without addition of extra reagents. The present protocol is compatible with various secondary amines and primary amines, and suitable for intermolecular and intramolecular reactions. Diverse unsymmetrical thioureas and oxazolidinethiones were efficiently obtained in good to excellent yields via a cascade reaction sequence.
