To provide an excellent amidite for synthesizing modified nucleic acid, which enables a protective group therein to be removed under a moderate condition, thereby stably producing a hydroxyl group-containing modified nucleic acid, and a method for synthesizing modified nucleic acid using the amidite. Specifically, an amidite for synthesizing modified nucleic acid, expressed by General Formula (I):
where X represents a base, Y represents a substituent, Z represents a protective group for protecting a hydroxyl group in the substituent, and Q represents one of a hydrogen atom, a hydroxyl group and a hydroxyl group protected by a protective group,
wherein the protective group can be removed in an aprotic solvent, and when the protective group is removed, the hydroxyl group emerges in the substituent, and a method for synthesizing modified nucleic acid using the amidite.
提供一种用于合成修饰核酸的优良酰胺试剂,该试剂可使其中的保护基在适度条件下被去除,从而稳定地产生含有羟基的修饰核酸,并提供一种使用该酰胺试剂合成修饰核酸的方法。具体而言,该酰胺试剂的通式表示为(I)式,其中X代表一种碱基,Y代表一种取代基,Z代表一种用于保护取代基中羟基的保护基,Q代表氢原子、羟基或被保护基保护的羟基中的一种,其中保护基可在无水溶剂中被去除,当保护基被去除时,羟基出现在取代基中,同时提供使用该酰胺试剂合成修饰核酸的方法。
