In recent years, oxazolidinone compounds have been discovered as a new antibiotic agent for the effective therapy to antibiotic-resistant species. In this work, we have studied the intramolecular cyclization of N-BOC-protected epoxy amine intermediate(1) under the acidic condition to afford oxazolidinone intermediate(2) and also tested the resolution of the amine intermediate(3) with several chiral acids to give a chiral oxazolidinone intermediate(4) for linezolid.
