A novel class of protecting compounds, particularly for amino acids, is based on 2,2 di nitrophenyl ethan- groups, particularly the groups wherein the nitro is in the para position. The ethyl group may be substituted, e.g. by an alkyl group, in the l- position. Preferred compounds include the alcohol or halide which are suitable for protecting acid functional groups, and esters, including activated and substituted esters, particularly the succinimidyl ester, for protecting amine groups. The invention includes methods of manufacture and use, together with protected amino acids.
一种新型保护化合物类,特别是用于氨基酸的,基于2,2-二硝基苯乙基基团,特别是硝基在对位的基团。乙基基团可以被取代,例如在1位上取代为烷基基团。首选化合物包括适用于保护酸官能团的醇或卤化物,以及酯类,包括活化和取代酯类,特别是琥珀酰亚胺酯,用于保护胺基团。该发明包括制造和使用方法,以及受保护的氨基酸。
