The preparation of D-penicillamine (5) was achieved by a single-step reaction of benzylpenicillin potassium salt (1) with arylamines (2, 7, and 13). The intermediates in these reactions should be the penicilloic acid α-amides. The structures of by-products formed in these reactions were also determined.
