Chemistry of carbamoyl disulfide protected derivatives of proline

Research output: Contribution to journalArticlepeer-review

9 Scopus citations


High‐yield methods have been devised for the synthesis of a series of alkyl and aryldithiocarbonyl derivatives of the α‐imino acid proline. The carbamoyl disulfide protecting groups were rapidly and quantitatively removed under a variety of reductive conditions, suggesting their potential value for orthogonal schemes of peptide synthesis.
