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.
