Penicillamine: An extractable chiral auxiliary providing excellent stereocontrol

A synthetic route for racemization-free incorporation of derivatives of penicillamine into the bislactim ether template is reported. Penicillamine-derived bislactim ethers exhibit excellent stereodiscrimination, and the chiral auxiliary can be removed fro
