Waltonは、2,3,5−トリ−O−アシル2(または3)−C−アルキルリボフラノシルハライドをクロロ第二水銀プリンまたはピリミジン化合物と反応させることにより調製される分枝鎖ヌクレオシドの合成を記載している(米国特許第3,480,613号)。1,2−O−イソプロピリデン−5−O−アシル−α−D−エリスロ−ペンタフラン−3−ウロースから出発してこの化合物をグリニャール試薬と反応させてC3において低級アルキル基を付加して、3−低級アルキル−D−リボフラノシルハライド中間体を調製した。次に、2つの経路のうちの一方を行った。第1の経路において、5−O−アシル−1,2−O−イソプロピリデン−3−低級アルキル−D−リボフラノースを酸性アルコール分解に付してアルキル5−O−アシル−3−低級アルキル−D−リボフラノシドを形成し;後者の化合物を、次に、アルキル2,3,5−トリ−O−アシル−3−低級アルキル−D−リボフラノシドにアシル化し;得られたリボフラノシドを、次に、塩基性加溶媒分解に付し、水性媒体中の強酸中でさらに加水分解することにより、遊離糖に転化することができる、または適切な溶媒中でのハロゲン置換反応によりハロゲノースに転化することができる。第2の経路において、不活性溶媒中で塩基性条件(ピリジン)下に5−O−アシル−1,2−O−イソプロピリデン−3−低級アルキル−D−リボフラノースをアシル化して3,5−ジ−O−アシル−1,2−O−イソプロピリデン−3−低級アルキル−D−リボフラノースを形成し、これを次に、強酸中で加水分解し、さらにアシル化して所望の中間体を得た。糖部分の2’−位または3’−位に分枝鎖を有する2−置換、6−置換または2,6−二置換のプリンヌクレオシドを、次に、2,3,5−トリ−O−アシル−D−リボフラノシルハライドを、トルエンまたはキシレンのような溶媒中にて100℃から140℃の温度でクロロ第2水銀2,6−二置換プリンと反応させることにより調製した。所望のピリミジノン塩基を有するヌクレオシドを、2,3,5−トリ−O−アシル−2(または3)−C−低級アルキル−D−リボフラノシルハライドから、2,4−ジアルコキシ−ピリミジンと反応させて1−(2,3,5−トリ−O−アシル2(または3)−C−低級アルキル−D−リボフラノシル)−4−アルコキシ−2(1H)−ピリミドンを形成することにより誘導し、これを、次に、アンモニアまたは第1もしくは第2アミンと反応させて、ピリミジノンのC−4にアミノ置換基を有する化合物を提供、または、酸性または塩基性条件下に加水分解して、C−4にヒドロキシ基を有するピリミジノン塩基を提供した。不運なことに、Walton合成は、複数の工程、特別の条件、および多数の毒性試薬を含む。
製薬活性化合物は、エステル化したプロドラッグ状態で投与されることができる。カルボン酸エステルが最も一般的に用いられ、ホスホン酸およびリン酸エステルは、生体内で加水分解できず、毒性副産物を生成することがあるので、使用頻度が低い(Erionらの米国特許第6,312,662号を参照)。環式ホスホン酸エステルおよびアリールエステル、特にフェニルおよびベンジルエステルと同様に、アシクロキシアルキルエステルをリン酸およびホスホン酸化合物用のプロドラッグとして用いる(Farquharら著、J.Pharm.Sci、(1983年)、第72(3)巻:324頁;Erionらの米国特許第6,312,662号)。ヌクレオシドと同様に、例えばホスホノ蟻酸およびPMEA(Adefovir;9−(2−ホスホニルメトキシ−エチル)アデニン)のようなホスホン酸類が、カルボン酸またはヌクレオシドのエーテル脂質プロドラッグが示すような抗ウイルス活性を示す(Gosselinらの米国特許第6,458,773号)。

次に
(f)要すれば、4−アミノ−1−(3,4−(独立して場合により保護されたヒドロキシ)−5−O−保護ヒドロキシメチレン−3−メチル−テトラヒドロフラン−2−イル)−1H−ピリミジン−2−オンを場合により脱保護して4−アミノ−1−(3,4−ジヒドロキシ−5−ヒドロキシメチル−3−メチル−テトラヒドロフラン−2−イル)−1H−ピリミジン−2−オン(VI)を形成する工程
