The dynamickineticresolution of racemic epichlorohydrin has been achieved via enantioselective asymmetric ring opening with TMSN3 catalyzed by the (salen)Cr(III)N3 complex 1. The resulting 3-azido-1-chloro-2-trimethylsiloxypropane product was obtained in high enantiomeric purity and incorporated into the synthesis of U-100592, a representative from a class of highly-promising aryl oxazolidinone antibacterial
