Abstract
A systematic study of the ring-closing metathesis (RCM) of unprotected oxytocin and crotalphine peptide analogues in water is reported. The replacement of cysteine with S-allyl cysteine enables RCM to proceed readily in water containing excess MgCl(2) with 30% t-BuOH as a co-solvent. The presence of the sulfur atom is vital for efficient aqueous RCM to occur, with non-sulfur containing analogues undergoing RCM in low yields.
