Preparation of β,β-Dialkyl Analogues of Cysteine Suitable for Peptide Synthesis

Article abstract of DOI:10.1021/jo00376a019

A general method is described for the preparation of cycteine derivatives that are substituted with one or two alkyl groups at the β-carbon.The synthesis is based on the sulfenylation of N^α-formyl-α,β-dehydro amino acid esters.The protected deh
