The synthesis of S-alkylated cysteine derivatives was carried out successfully in the presence of 1,1,3,3-tetramethylguanidine. Alkylation proceeded in high yields on unprotected amino acids and peptides containing a sulfhydryl group.
在1,1,3,3-四甲基胍的存在下成功进行了S-烷基化的半胱氨酸衍生物的合成。在未保护的氨基酸和含有巯基的肽上,烷基化反应高收率地进行。
