The title compound has efficiently been synthesized by the skeletal rearrangement of the protected isopenicillin N sulfoxide and the subsequent hydrolysis of the thiazoline ring.

The disulphide corresponding to the above thiol has been synthesised but all attempts to reduce this substance to the thiol have been unsuccessful, although an alternative procedure, via a thiomercury intermediate, enabled the thiol to be generated in situ; the properties of this thiol, however, are not in accord with those described for a putative intermediate in penicillin biosynthesis.
