Synthesis of Oxazolidinones by a Hypervalent Iodine Mediated Cyclization of N-Allylcarbamates

Abstract

The preparation of oxazolidinones by the hypervalent iodine mediated cyclization of allylcarbamates is described. A versatile range of substrates can be converted into substituted oxazolidinones primed for further transformations. Derivatization of the products at both ends is demonstrated. A preliminary attempt at the enantioselective formation of an oxazolidinone using a chiral iodane is also presented. (Figure presented.).
