text] Rapid, facile routes to the TFA-cleavable 4,5,6-trimethoxy-2-mercaptobenzyl and 1-(2,4-dimethoxyphenyl)-2-mercaptoethyl classes of auxiliaries for cysteine-free native chemical ligation are described. Rapid synthesis, coupled with mild cleavage conditions will undoubtedly broaden the utility of such auxiliaries, particularly where chemically fragile peptide modifications such as glycosylation are
[反应:参见正文]快速,简便的途径可用于TFA可裂解的4,5,6-三甲氧基-2-巯基苄基和1-(2,4-二甲氧基苯基)-2-巯基乙基类助剂,用于无半胱氨酸的天然化学连接被描述。快速合成,加上温和的裂解条件,无疑将拓宽此类助剂的用途,特别是在存在化学上易碎的肽修饰(例如糖基化)的情况下。
