ChemInform Abstract: Cyclization Reactions of β,γ‐Unsaturated Derivatives of Carbonic Acid. Part 9. Regiochemistry of Electrophilic Cyclofunctionalization of β,γ‐Unsaturated Carbamic Acid Esters with Bromine ‐ Synthesis of Oxazolidine‐2‐ones and Tetrahydro‐2H‐1,3‐oxazine‐2‐ones.
Abstract Treatment of the urethanes (I) with bromine leads to mixtures of the adducts (II) (spectroscopically identified, but not isolated), the oxazolidinones (III) [obtained only in the cases (IIIa)‐(IIIf)], and the tetrahydrooxazinones(IV) [obtained in all cases except (IVd)].
