Abstract
A new practical method for the synthesis of a non-cross-linked polystyrene supported 2-phenylimino-2-oxazolidine chiral auxiliary is reported. This method started from the same material as in a previous synthesis, N-Boc- L-tyrosine ethyl ester, but the overall yield was 42.5%, which was higher than the copolymerisation method.

Abstract
A new chiral auxiliary, non-cross-linked polystyrene-supported oxazolidine-2-selone was synthesized using N-Boc-l-tyrosine ethyl ester as starting material. The structure of the target product was detected by IR, NMR, elemental analysis, and the spectrum result was consistent with the molecular structure.
