Description
本発明では、ヒドロキシプロリンをエステル化する。
本発明では、エステル反応に次いでN−アシル化反応を行う
N−アシル化は、好ましくは、塩基共存下でアシルハライド、もしくは二炭酸ジアルキルエステル等のアシル化試薬と反応させるが、原料を仕込む順番としては、エステル化した粗体に塩基、水の順で加え、次いでアシル化試薬を加えることが好ましい。
カラム:CAPCELL PAK C18(SG120),5μm 150mm*4.6mmφ(資生堂)
移動層A:5mMドデシル硫酸ナトリウム+20mMリン酸緩衝液(pH2.8調整)
移動層B:アセトニトリル
A/B=80/20(10分)−10分→45/55(25分)
流速:1.0ml/min
温度:40℃
検出器:UV 210nm
保持時間 1.8分:トランス−4−ヒドロキシ−L−プロリン
4.1分:トランス−4−ヒドロキシ−L−プロリンメチルエステル
8.7分:トランス−ベンジルオキシカルボニル−4−ヒドロキシ−L−プロリンメチルエステル
また、実施例で使用した試薬は、特に注記のない限り市販の試薬1級グレード品を使用した。
温度計、ジムロート、攪拌機を備えた3000mlの4つ口フラスコにメタノール1771g、トランス−L−ヒドロキシプロリン354g(2.70モル)を加えた。15℃に冷却し、攪拌しながら滴下ロートを用いて塩化チオニル193gを1時間かけて滴下した。滴下終了後60℃に昇温して5時間熟成した。次いで温度を保ちながら13kPaで減圧濃縮でメタノールを留出させ、スラリーを得た。スラリー中のトランス−4−ヒドロキシ−L−プロリンメチルエステルの含量は2.58モル(収率95.7%)であった。
実施例1と同様の操作で得た、トランス−4−ヒドロキシ−L−プロリンメチルエステル0.18g(1.0mmol)に水2.0gを加え、炭酸水素ナトリウム0.17g(2.1mmol)を加えた。さらに氷冷下でベンジルオキシカルボニルクロリド0.15gを加え、25℃で2時間熟成した。
実施例1と同様の操作で得た、トランス−4−ヒドロキシ−L−プロリンメチルエステル0.36g(2.0mmol)に水2.0gを加え、25%水酸化ナトリウム水溶液0.3g(4.1mmol)を加えた。さらに氷冷下でベンジルオキシカルボニルクロリド0.3gを加え、25℃で2時間熟成した。
実施例1と同様の操作で得た、トランス−4−ヒドロキシ−L−プロリンメチルエステル0.36g(2.0mmol)にトルエン2.0gを加え、トリエチルアミン0.2g(4.1mmol)を加えた。さらに氷冷下でベンジルオキシカルボニルクロリド0.3gを加え、25℃で2時間熟成した。
実施例1と同様の操作で得た、トランス−4−ヒドロキシ−L−プロリンメチルエステル0.36g(2.0mmol)にメタノール2.0gを加え、トリエチルアミン0.2g(4.1mmol)を加えた。さらに氷冷下でベンジルオキシカルボニルクロリド0.3gを加え、25℃で2時間熟成した。
特許文献1記載の方法を追試し、収率を確認した。
