A convenient selective protection of the α-amino carboxyl group of amino acids bearing reactive side chain groups such as arginine, asparagine, glutamine, cysteine, histidine, serine and lysine, using 4-alkoxy-1,1,1-trifluoro[chloro]alk-3-en-2-ones is reported. The reactions were performed without esterification of the carboxyl group and N-deprotection was carried out using a six molar solution of hydrochloric acid.
报告了一种利用 4-烷氧基-1,1,1-三氟[氯]烷-3-烯-2-酮对带有反应性侧链基团的氨基酸(如精氨酸、天冬酰胺、谷氨酰胺、半胱氨酸、组氨酸、丝氨酸和赖氨酸)的δ-氨基羧基进行选择性保护的简便方法。反应是在没有羧基酯化的情况下进行的,并使用六摩尔盐酸溶液进行 N-脱保护。
