P-O3′ (ζ) and P-05′ (α) boonds is significantly greater for the 2′-phosphate group than for the 3′-phosphate grooup. These results point towards preferential 2′→5′ rather than 3′→5′ base stacked structures in all of these synthetic models of the lariat. This is especially the case for the branched trimer 20 and the pentamer 27 which are part of a naturally occurring lariat structure. Note that the strongest

The present invention aims to provide a method of producing, more efficiently at a high purity, a phosphoramidite preferable for the production (synthesis) of a nucleic acid. Using a coupling reaction of an ether represented by the following chemical formula (105), an enantiomer, tautomer or stereoisomer thereof, or a salt thereof, and a glycoside compound, phosphoramidite that enables efficient synthesis of nucleic acid can be obtained:
wherein n is a positive integer, and R and R' are the same or different and each is a hydrogen atom or a hydroxyl-protecting group.
本发明旨在提供一种方法,以更高的纯度更有效地生产一种优选用于生产(合成)核酸的亚磷酰胺。通过以下化学式(105)所代表的一种醚、其对映体、同分异构体或立体异构体或其盐与一种糖苷化合物的偶联反应,可获得能高效合成核酸的亚磷酰胺:
其中 n 为正整数,R 和 R' 相同或不同,且各自为氢原子或羟基保护基团。
