N-lsobutoxycarbonyl protected L-alanine was condensed with 4-phenylbenzaldehyde in a crystallization-controlled process to give the corresponding c is-oxazolidinone derivative as the sole product in high yield this underwent enolization and benzylation with the typical high degree of stereoselectivity observed in the SROSC involving this class of compounds.
