methiodides and sulphones derivedfrom the β-methylthioethyl esters of amino-acids and peptides are split to the parent carboxylic acids under extremely mild alkaline conditions. Methods for the preparation of β-methylthioethyl esters of amino-acids are described and their use in peptide synthesis is explored. The β-methylthioethyl ester group is advocated as a useful new carboxyl protecting group
