t-amyl chloroformate (I). Reagent I was prepared by an improved method, using a stock solution of phosgene in toluene. Reagent II was converted to t-amyl azidoformate (III), as in the case of the t-butyl derivative, and reagent III was used for introducing the t-amyloxycarbonyl (AOC) group into free amino acids, amino acid esters, and peptides. Various new AOC-amino acids were synthesized by the present
通过氯甲酸叔戊酯 (I) 的直接肼解,以令人满意的收率合成了氨基甲酸叔戊酯 (II)。试剂 I 是通过改进的方法制备的,使用光气在甲苯中的储备溶液。试剂II转化为叠氮基甲酸叔戊酯(III),与叔丁基衍生物的情况一样,试剂III用于将叔戊基氧羰基(AOC)基团引入游离氨基酸、氨基酸酯和肽中. 通过本方法合成了多种新的AOC-氨基酸。发现氯仿会抑制试剂 III 与氨基酸酯的反应。本文描述了一种获得大量无水肼的实用且安全的方法。
