50mlのテトラヒドロフランに入れた17α,21−ジヒドロキシ−プレグナ−4,9−ジエン−3,20−ジオンが1g(2.87mM)で酪酸トリフルオロエチルが10mlの混合物をカンジダ・シリンドラセアのリパーゼを5g存在させて45℃で8−10時間反応させたが、ここでは、規則的な時間的間隔でリパーゼを1gづつ添加した。この1番目の反応段階が終了した時点で、前記リパーゼを濾別し、その濾液を真空下で濃縮した後、その残留物をテトラヒドロフランで3回取り上げた。その結果として得た残留物に酪酸トリフルオロエチルを更に10mlおよびテトラヒドロフランを50ml加え、その結果として生じた溶液に枯草菌のプロテアーゼを0.8g加え、その懸濁液を45℃で2日間撹拌し、更にプロテアーゼを規則的な時間的間隔で加えて、全体で80mg添加した。前記プロテアーゼを濾別し、その濾液を真空下で除去した後、その残留物をシリカゲルカラム使用クロマトグラフィーにかけて、ジクロロメタン/メタノールが99:1の混合物を用いた。極性が低い方の画分に蒸発を受けさせることで、17α,21−ジブタノイル−プレグナ−4,9−ジエン−3,20−ジオンを1g(2.06mM)得た。
100mlのアセトンに入れた17α,21−ジヒドロキシ−プレグナ−4,9−ジエン−3,20−ジオンが1g(2.879mM)で酪酸トリフルオロエチルが10mlの混合物をカンジダ・シリンドラセアのリパーゼを5g存在させて45℃で8−10時間反応させたが、ここでは、規則的な時間的間隔でリパーゼを1gづつ添加した。この反応が終了した後、前記リパーゼを濾別し、その濾液を真空下で濃縮した後、その残留物をアセトンで3回取り上げた。半固体状の残留物をシリカゲルカラム使用クロマトグラフィーにかけてジクロロメタン/メタノールが99:1の混合物を用いることで精製を行った。極性が低い方の成分を除去することで、より豊富な画分を得た後、それに蒸発を受けさせることで、17α−ヒドロキシ−21−ブタノイル−プレグナ−4,9−ジエン−3,20−ジオンを0.95g(2.29mM)得た。
50mlのメチルエチルケトンに入れた17α,21−ジヒドロキシ−プレグナ−4−エン−3,20−ジオンが1gで酪酸トリフルオロエチルが10mlの混合物をカンジダ・シリンドラセアのリパーゼを5g存在させて45℃で8−10時間反応させたが、ここでは、規則的な時間的間隔でリパーゼを1gづつ添加した。この反応が終了した後、前記リパーゼを濾別し、その濾液を真空下で濃縮した後、その残留物を溶媒で3回取り上げた。半固体状の残留物をシリカゲルカラム使用クロマトグラフィーにかけてジクロロメタン/メタノールが99:1の混合物を用いることで精製を行った。豊富な方の画分に蒸発を受けさせることで、17α−ヒドロキシ−21−ブタノイル−プレグナ−4−エン−3,20−ジオンを0.89g(2.14mM)得た。
4g(11.6mM)の17α,21−ジヒドロキシ−プレグナ−4,9−ジエン−3,20−ジオンと20mgのトリフルオロ酢酸を20mlのジオキサンと10mlのオルト酪酸エチルに入れて100℃で5時間反応させた後、低沸点の塔頂溜分(head fraction)を留出させた。その溶液を冷却した後、1モル規定の酒石酸溶液を5ml用いて処理し、そして40−50℃に約5分間加熱することで、17α−ブタノイル−21−ヒドロキシ−プレグナ−4,9−ジエン−3,20−ジオンを得た。溶媒を真空下で蒸発させて除去した後、その残留物をジオキサンで繰り返し取り上げた。その結果として得た残留物を200mlのアセトンに溶解させた後、オクタデカン酸トリフルオロエチル(オクタデカノイルクロライドとトリフルオロエタノールから調製)を12g、カンジダ・シリンドラセアのリパーゼを20g加えて、その結果として生じた懸濁液を50℃で8−10時間撹拌したが、ここでは、規則的な時間的間隔でC.シリンドラセアのリパーゼを2gづつ加えた。前記リパーゼを濾別し、その濾液を真空下で濃縮した後、その残留物をシリカゲルカラム使用クロマトグラフィーにかけてジクロロメタン/メタノールが98.5:1.5の混合物を用いた。混ぜ物が入っていない画分に蒸発を受けさせることで、17α−ブタノイル−21−オクタデカノイル−プレグナ−4,9−ジエン−3,20−ジオンを4.9g(7.17mM)得た。
段階a:20mlの水に2gのNaOHを入れることで生じさせた溶液にテトラヒドロフランを25mlおよび17α,21−ジヒドロキシ−プレグナ−4,9−ジエン−3,20−ジオンを5g(14.5mM)加えた。この混合物を0℃で撹拌した後、クロロ蟻酸アリルを2.4ml滴下した。この温度で撹拌を約0.5時間行った後、その混合物を塩酸で注意深く中和し、そしてジクロロメタンで抽出した。その有機抽出液に濃縮を真空下で受けさせた後、その残留物に次の段階の反応を受けさせた。
− 17α,21−ジブタノイル−プレグナ−4−エン−3,20−ジオン(融点101℃、イソプロピルエーテル);
− 17α−プロピオニル−21−ヒドロキシ−プレグナ−4−エン−3,20−ジオン(融点114℃、イソプロピルエーテル);
