was ascertained by purification via the quinine and ephedrine salts of t-butoxy-carbonyl-adamantylalanine. The new amino acid shall be used for studies of structure-activity relationships of phenylalanine and leucine residues in biologically active peptides. In addition, a convenient synthesis in excellent yield of the starting material, 2-(1-adamantyl)-ethanal, by Pfitzner-Moffat oxidation of 2-(
由于其总体空间上与苯丙氨酸类似物碳硼烷基丙氨酸相似,因此该标题化合物是通过Patel&Worsley的改良Strecker合成方法制备的。(S)-(-)-α-甲基苄基胺在合成中的应用,[α] D随着质子化增加的正趋势以及合成的非对映二肽的薄层色谱行为均强烈表明了不对称结构碳原子是S(天然L)。通过t的奎宁和麻黄碱盐纯化,确定其光学纯度。-丁氧基羰基-金刚烷丙氨酸。新的氨基酸将用于研究生物活性肽中苯丙氨酸和亮氨酸残基的构效关系。另外,描述了通过2-(1-金刚烷基)-乙醇的Pfitzner-Moffat氧化,以优异的产率合成起始原料2-(1-金刚烷基)-乙醛。
