Title (EN) PROCESS FOR PRODUCING NUCLEOSIDE
(FR) PROCÉDÉ DE PRODUCTION DE NUCLÉOSIDE
(JA) ヌクレオシドの製造方法
Abstract: front page image
(EN)A process for producing an NC-type purine nucleoside readily has been demanded. Thus, disclosed is a process for producing a purine nucleoside represented by formula (I') or a salt thereof, which comprises reacting a pyrimidine nucleoside represented by formula (I) or a salt thereof with a purine nucleic acid base represented by formula: B'H in the presence of a Lewis acid.
(FR)L'invention porte sur un procédé de production aisée d'un nucléoside purique de type NC. Ainsi, l'invention porte sur un procédé de production d'un nucléoside purique représenté par la formule (I') ou d'un sel de celui-ci, qui comprend la réaction d'un nucléoside pyrimidique représenté par la formule (I) ou un sel de celui-ci avec une base d'acide nucléique purique représentée par la formule : B'H en présence d'un acide de Lewis.
(JA) NC型プリンヌクレオシドを簡便に製造する方法が求められている。 式(I)で表されるピリミジンヌクレオシドまたはその塩を、ルイス酸存在下で、式B'Hで表されるプリン核酸塩基と反応させることを特徴とする、式(I')で表されるプリンヌクレオシドまたはその塩を製造する方法。
