The present invention provides a photolabile protecting group that can be removed by light irradiation under mild conditions. More specifically, the present invention provides a method comprising protecting a reactive functional group (e.g., a hydroxyl group, amino group, carboxyl group, carbonyl group, phosphodiester group, etc.) by the photolabile protecting group, and then removing the photolabile protecting group simply by light irradiation under neutral conditions.
The present invention relates to a compound represented by Formula (3):
wherein Ar1 is an optionally substituted aromatic or heteroaromatic ring, Ar2 is an optionally substituted aryl or heteroaryl group, X is a leaving group, and n is an integer of 1 or 2; and a method of protecting and deprotecting an amino group etc. using the compound.
本发明提供了一种光敏保护基,可以在温和条件下通过光照辐射去除。更具体地说,本发明提供了一种方法,包括使用光敏保护基保护反应性官能团(例如,羟基、氨基、羧基、酮基、磷酸二酯基等),然后仅通过中性条件下的光照辐射去除光敏保护基。本发明涉及由式(3)表示的化合物:其中Ar1是可选择取代的芳香或杂芳环,Ar2是可选择取代的芳基或杂芳基团,X是离去基,n是1或2的整数;以及使用该化合物保护和去保护氨基等的方法。
