ClickChemistry點(diǎn)擊化學(xué)（DBCO）高效的偶聯(lián)反應(yīng)

一：概述

  點(diǎn)擊化學(xué)(Click chemistry)，又譯為"鏈接化學(xué)"、"速配接合組合式化學(xué).二苯并環(huán)辛炔（ADIBO，DBCO）是用于應(yīng)變促進(jìn)的炔疊氮化物環(huán)加成（spAAC）（一種無銅Click化學(xué)反應(yīng)）的*具反應(yīng)性的環(huán)炔。

這是一種胺反應(yīng)性NHS酯，可將反應(yīng)性部分輕松連接*幾乎任何伯或仲胺基團(tuán)，例如蛋白質(zhì)，肽或小分子胺基團(tuán)。

DBCO立即與疊氮化物反應(yīng)。該反應(yīng)速率遠(yuǎn)高于銅催化的反應(yīng)速率以及與許多其他環(huán)辛炔的反應(yīng)速率。與某些其他環(huán)辛炔不同，DBCO不與四嗪發(fā)生反應(yīng)-這允許疊氮化物與DBCO和反式環(huán)辛烯與四嗪進(jìn)行正交共軛。

二：原理

點(diǎn)擊化學(xué)反應(yīng)主要有4 種類型

1.環(huán)加成反應(yīng)

2.親核開環(huán)反應(yīng)

3.非醇醛的羰基化學(xué)

4.碳碳多鍵的加成反應(yīng)

三：反應(yīng)特征

1. 反應(yīng)原料容易得到
2. 對于氧氣、水不敏感
3. 產(chǎn)率相對較高
4. 產(chǎn)物的立體選擇性好
