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
