Abstract
Description
Aは、A1、A2又はA3であり;
R1は、水素、アジド、C1-6アルキル又はC1-3アシルであり;
Ra1及びRa2は、独立して、水素又はヒドロキシルであり;
Rb1及びRb2は、水素又は−O2CR2であり;
R2は、C1-10アルキル又はフェニルである)
該方法は、以下の工程:すなわち、
(i)I及びDMAPを不均一水性溶媒混合物に溶解し、水性塩基を加えて、pHを7〜13に調整し;
(ii)場合により、十分な飽和水性NaClを加えて、二相反応混合物を生成し;
(iii)アシル化剤及び、pHを7〜13に維持するに十分な追加の塩基を加え;
(iv)反応を監視し、変換が満足するレベルに到達した時に、前記アシル化剤及び前記塩基の添加を止め;
(v)場合により、O−アシルヌクレオシドを薬学的に許容され得る酸と接触させて、O−アシルヌクレオシドの酸付加塩の単離を可能にすることを含む。
イソ酪酸 (2R,3S,4S,5R)−5−(4−アミノ−2−オキソ−2H−ピリミジン−1−イル)−2−アジド−3,4−ビス−イソブチリルオキシ−テトラヒドロ−フラン−2−イルメチルエステル
イソ酪酸 5−(4−アミノ−2−オキソ−2H−ピリミジン−1−イル)−2−アジド−3,4−ビス−イソブチリルオキシ−テトラヒドロ−フラン−2−イルメチルエステル
イソ酪酸 2−(6−アミノ−プリン−9−イル)−4−イソブチリルオキシ−5−イソブチリルオキシメチル−テトラヒドロ−フラン−3−イルエステル
4−アミノ−1−((2R,3S,4S,5R)−5−アジド−3,4−ジヒドロキシ−5−ヒドロキシメチル−テトラヒドロ−フラン−2−イル)−1H−ピリミジン−2−オン(3、6.0g、18.01mmol)、THF(35mL)、ブライン(10mL)及びDMAP(0.2g)の溶液を、十分なブラインで処理して二相溶液(約2mL)を生成した。得られた二相混合物を約5℃に冷却し、イソブチロイルクロリド及び50%水性KOHを、反応混合物のpHを約8.5に維持する速度で、同時に加えた。反応をHPLCにより監視し、全出発物質が消費される迄、添加を継続した。HPLC分析は、トリ−及びテトラ−アシル生成物が存在することを示した。反応混合物のpHを希釈H2SO4により、約1.5に調整し、反応物を一夜撹拌して、いかなるテトラ−アシル化生成物をも加水分解した。生成物をEtOAc中で抽出し、合せた抽出液を水で徹底的に洗浄し、pHを約1.5mLに調整した。得られたEtOAc溶液を乾燥し(MgSO4)、濾過し、蒸発させて、4 7.8gを得、これは85.3%と分析された。
3(1.0g、3.00mmol)、DMAP(37mg)、THF(1.0mL)及び水(4.0mL)のスラリーに、50%NaOHを、pHが7〜8となる迄加えた後、飽和NaHCO3でpH9.5に調整した。カルボニルジイミダゾール(1.3g、9.0mmol)をイソ酪酸(0.8g、9.00mmol)のTHF(10mL)溶液に加え、更なる泡立ちが全くなくなる迄、撹拌を継続した。後者の溶液を、3を含有するスラリーに、RTでゆっくり加えた。塩基を加えて、pHを約9に維持した。HPLC分析は、モノ−、ジ−及びトリアシル化生成物の混合物を示し、後者の2つが優勢であった。反応は、全物質が生成物に変換する迄、アシルイミダゾールが加えらなら、完了まで進行するであろう。
