AbstractThe thiol‐induced fragmentations of sulfenyl thiocarbonates (RSSCOOCH3) leading to mixed disulfides was applied to the synthesis of open‐chain asymmetrical cystine peptides. Various fragments of insulin containing the disulfide bridge between A20 and B19 were prepared by this method.

N-Adamantane-substituted tetrapeptide amides and the pharmacologically acceptable salts thereof are disclosed herein. These compounds are analogs of enkephalin wherein the methionine or leucine of position 5 has been substituted by an adamantyl amide and the glycine of position 2 has been substituted by various amino acid residues. Optionally the tyrosine of position 1 and the phenylalanine of position 4 may be substituted by various amino acid residues. These compounds exhibit agonist activity at opiate receptor sites and are useful as analgesics.
