Abstract

An efficient and general iodocarbamation of benzyl N‐homopropargylcarbamates has been developed by using iodine as the electrophilic agent. This regio‐ and stereoselective cyclization yielded (E)‐6‐iodomethyleneoxazinan‐2‐ones, which can be further transformed through palladium cross‐coupling reactions followed by hydrogenation to produce 1,3‐oxazinan‐2‐ones.
