We describe an efficient method for constructing cyclic polysulfide-co
ntaining peptides. The synthesis uses commercially available bis-(tetr
abutylammonium) hexasulfide (BTH) and can be performed in aqueous solu
tion, Preliminary structural analyses indicate that varying the number
of sulfur atoms affects the conformation of the peptide in solution.
