The chemical conversion of C-terminal glycines in peptides into taurine
Abstract
The first chemical conversion of C-glycine in dipeptides into taurine has been achieved using a general substitution of a sulpho group for a halogeno or mesyl group via the corresponding amino acid 2-halogenoethyl-or 2-methanesulphonyloxyethyl-amides, each of which was prepared from the ethanolamide obtained by LiBH4 reduction of a protected dipeptide containing a C-glycine ester.
