查询词典 field and track

The process does not depends on catalytic hydrogenization method, has simple reaction condition, high reactant yield all over 75%, can use TLC to track the whole reaction process, and is more suitable to the transformation of function group in the organic synthesis field as the result of N-Boc or N-Cbz derivative is easy to loss protective reaction, which has spreading application prospect.

该方法不依赖于催化氢化方法，反应条件简单，反应产物产率高，均在75％以上，反应过程可用TLC进行跟踪，且由于N-Boc或N-Cbz衍生物更易发生去保护反应，在有机合成领域更适宜于官能团的转化，具有广阔的应用前景。
