Indion 190 수지의 존재하에서 di-tert-butoxypyrocarbonate (Boc)2O를 이용한 아민의 N-Boc protection의 효과적인, 화학적 선택성적인,실용적인 실험안. 수지는 반응혼합물로부터 쉽게 분리되었고 활 성의 감소 없이 재사용되었다. 간단한 workup, 온화한 조건, 짧은 반응시간, 높은 수율은 이 방법의 두드 러진 특색들이다.

An efficient, chemoselective and practical protocol for N-Boc protection of amines using di-tertbutoxypyrocarbonate (Boc)2O in presence of Indion 190 resin. Resin was easily separated from the reaction mixture by filtration and reused in subsequent reactions without any apparent loss of activity. Simple workup, mild condition, short reaction time and high yield are some of the striking features of the present process.
