A guanidino group in an amino acid or a peptide can be protected with a specific protective group, i.e. lower alkoxybenzenesulfonyl group or tri-lower alkylbenzenesulfonyl group, and the protective group may easily be removed without affecting the amino acid or the peptide to be derived from the protected amino acid or peptide. Thus, the method is useful in the related chemical industries, especially in the peptide synthesis.
氨基酸或肽中的鸟氨酸基团可以用特定的保护基保护,例如较低的烷氧基苯磺酰基或三个较低烷基苯磺酰基,而且保护基可以轻易地去除,而不影响从保护的氨基酸或肽中得到的氨基酸或肽。因此,这种方法在相关的化学工业中特别是肽合成中是有用的。
