A method for the preparation of (2R,3S) nitrogen protected arylserine esters is described. The method consists of rhodium mediated insertion of tert-butylcarbamate into the corresponding 3-keto-2-diazoester, affording the N-protected alpha-amino-beta-ketoester, followed by asymmetric reduction/dynamic resolution to afford the corresponding N-protected 3-arylserine esters in good chemical yield, and in most cases high enantiomeric excess.
