Alkenyl oxazolidinones 5 have been made from the urethane derivatives 4 of diphenylphosphinoyl epoxy alcohols 1 by a tandem intramolecular ring closure - Horner-Wittig elimination sequence. The stereoisomers of diphenylphosphinoyl epoxy alcohols containing further chiral centres have been made by enantio- and diastereoselective epoxidation, and converted stereospecifically to alkenyl oxazolidinones with 1,4-related chiral centres across a controlled geometry double bond.
