rearrangement for the synthesis of cyclic 1-(arylamino) carboxylates from readily available 2,2,2-trichloromethyl carbinols and anilines is described. The method demonstrates good scope, with a large variety of anilines providing direct access to several novel cyclic 1-(arylamino) carboxylates. The reaction is robust and has been shown to provide comparable results on kilogram scale. The reaction is diastereospecific
selectivity. trans-Oxazolidinones were prepared from acyclic secondary N-mesyloxycarbamates using Rh2(oct)4. The selectivity was reverted with a cytoxazone N-mesyloxycarbamate precursor using large chiralrhodium(II) carboxylate complexes, affording the corresponding cis-oxazolidinone. This orthogonal selectivity was used to achieve the formal synthesis of (−)-cytoxazone.
