Abstract
กระบวนการแบบหนึ่งเพื่อทำให้บริสุทธิ์และแยกนิวคลีโอไซด์ซึ่งอุดมสมบูรณ์ด้วยเบตาแอโนเมอร์ ประกอบ รวมด้วย (a) การจัดเตรียมของผสมซึ่งมี R" และนิวคลีโอไซด์ซึ่งอุดมด้วยเบตา- แอโนเมอร์ซึ่งมีสูตร: (สูตรเคมี) (IB) ; ซึ่งแต่ละหมู่ของ x ได้คัดเลือกอย่างอิสระจากหมู่ป้องกันไฮดรอกซีและ R' เป็นนิวคลิโอเบสของสูตร (สูตรเคมี) ซึ่ง w คือหมู่ป้องกันแอมิโน, และ R" เป็นนิวคลิโอเบสของสูตร (สูตรเคมี) ซึ่ง W' คือหมู่ป้องกันแอมิโนหรือไฮโดร เจน; ในตัวทำละลายซึ่งมีจุดเดือดสูง; (b) การเจือจางส่วนผสมด้วยตัวทำละลายอินทรีย์จากหมู่ซึ่งประกอบด้วยอีเธอร์ เอสเทอร์และไนไทรล์ (c) การเติมส่วนผสมของปฏิกิริยาซึ่งเจือจางแล้วสู่สารละลายกรดในน้ำ, และ (d) การคงไว้ของส่วนผสมซึ่งเป็นกรดตามที่ได้เตรียมขึ้นแล้วที่อุณหภูมิตั้งแต่ 70 ํ ถึง 100 ซ. จนกระทั่งได้ตกตะกอนผลิตภัณฑ์ของสูตร IB ที่ W ในตอนนี้เป็น W'จะตก ตะกอน: สิทธิบัตรยา A process for purifying and separating beta-rich nucleosides consists of (a) preparation of mixtures containing R "and beta-rich nucleosides. - an anomer which has the formula: (chemical formula) (IB); Each group of x was independently selected from the anti-hydroxy group and R 'is the nucleobase of the formula (chemical formula) where w is the amino protective group, and R "is the nucleobase. Of the formula (chemical formula) in which W 'is the amino or hydrogens protective group; In solvents having a high boiling point; (b) Dilution of the mixture with an organic solvent from a group containing ether. Ester and nitrile (c) the addition of the diluted reaction mixture to aqueous acidic solution, and (d) the preservation of the prepared acidic mixture at temperatures from 70 ํ to 100 h until the product of formula IB was precipitated, where W now is W 'will precipitate: drug patent
