THE MICHAEL ADDITION OF SULFUR ANIONS TO β,β-SUBSTITUTED Nα-FORMYL-α,β-DEHYDROAMINO ACID ESTERS

The addition of lithium benzylthiolates to Nα-formyl-α,β-dehydro-α-amino acid esters gave protected Nα-formyl-β-S-benzyl-β,β-dialkylcysteine esters.Hydrolysis and Nα-protection produced β,β-dialkyl-cysteines which can be u

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

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 Nα-formyl-α,β-dehydro amino acid esters.The protected deh
