一:概述
點擊化學(Click chemistry),又譯為"鏈接化學"、"速配接合組合式化學.二苯并環(huán)辛炔(ADIBO,DBCO)是用于應變促進的炔疊氮化物環(huán)加成(spAAC)(一種無銅Click化學反應)的*具反應性的環(huán)炔。
這是一種胺反應性NHS酯,可將反應性部分輕松連接*幾乎任何伯或仲胺基團,例如蛋白質,肽或小分子胺基團。
DBCO立即與疊氮化物反應。該反應速率遠高于銅催化的反應速率以及與許多其他環(huán)辛炔的反應速率。與某些其他環(huán)辛炔不同,DBCO不與四嗪發(fā)生反應-這允許疊氮化物與DBCO和反式環(huán)辛烯與四嗪進行正交共軛。
二:原理
點擊化學反應主要有4 種類型
1.環(huán)加成反應
2.親核開環(huán)反應
3.非醇醛的羰基化學
4.碳碳多鍵的加成反應
三:反應特征
1. 反應原料容易得到
2. 對于氧氣、水不敏感
3. 產率相對較高
4. 產物的立體選擇性好
