Fmoc, Boc and Pbf were used respectively to protect α - amido, side amido and side guanidine group.
对于α-氨基仍采用Fmoc保护策略, 侧链氨基用二碳酸二叔丁酯引入叔丁氧羰基来保护,侧链胍基用酸敏感保护基2,2, 4,6,7-五甲基二氢苯并呋喃-5-磺酰基来保护.
In particular, the invention is concerned with amido piperazine derivatives.
具体地说, 本发明涉及酰氨基哌嗪衍生物.
The advance in the research of amido podands and structure - extraction ability is reported in this paper.
