Abstract
Description
(1)式(1)で表される3,5−ジヒドロキシ−6−ヘプテン酸誘導体(式中、Rは、炭素数1〜4のアルキル基である)を炭素数1〜4の低級アルコール含有溶媒と接触させる過程を含む方法であって、酸化性物質の含有量を可及的に低下しめたアルコール含有溶媒を使用し、3,5−ジヒドロキシ−6−ヘプテン酸誘導体に含有される不純物量を抑制したことを特徴とする3,5−ジヒドロキシ−6−ヘプテン酸誘導体の製造方法。
(3)上記アルコール含有溶媒中の酸化性物質の含有量を、式(1)で示される3,5−ジヒドロキシ−6−ヘプテン酸誘導体に対して0.05モル当量以下にせしめた上記(1)又は(2)に記載の製造方法。
(4)式(1)中のRが、メチル基又はエチル基である上記(1)、(2)又は(3)に記載の製造方法。
(5)上記アルコール含有溶媒中のアルコール類が、メタノール、エタノール、又はイソプロパノールである上記(1)〜(4)のいずれかに記載の製造方法。
(6)酸化性物質の含有量を式(1)で表される3,5−ジヒドロキシ−6−ヘプテン酸誘導体に対し0.05モル当量以下にせしめた上記アルコール含有溶媒中のアルコール類が、原料アルコールを蒸留したものであるか、又は原料アルコールを還元剤で処理したものである上記(1)〜(4)のいずれかに記載の製造方法。
上記製造過程で使用されるアルコール含有溶媒中のアルコール類は、元来それほど安定な物質ではない。一時的に高温にさらされると、その一部が分解して酸化性物質が生じ、該溶媒中に含有されているものと思われる。脱着、脱離の操作、及びその後に次の処理に移行されるまでの数時間〜数日間の長時間、目的物である3,5−ジヒドロキシ−6−ヘプテン酸誘導体が該アルコール含有溶媒と接触するという点で、アルコール類に含有される酸化性物質は、その量が微量であっても、本発明の目的物質の製造における液体クロマトグラフィーなどの過程において重大である。

実施例1
市販の試薬特級のイソプロパノールを常圧蒸留により160倍に濃縮し、濃縮液と留出液を得た。得られた留出液を再度160倍に濃縮する蒸留操作をさらに3回繰り返し、得られた各イソプロパノール液中に含有される酸化性物質の量(mgH2O2/g)を測定した。その結果を、表1に示す。
(3R,5S)DOLE500mgを市販の試薬特級のイソプロパノール(IPA)0.64ml(0.5g相当)に溶解した。一方、9.26mmol/gのH2O2水溶液を1.0035g秤りとり、上記と同じ市販の試薬特級のイソプロパノールで10mlに定容し、0.929mmol/g H2O2−IPA溶液を調製した。
市販のイソプロパノール9mLに(3R,5S)DOLE240mgを溶解させた。加速試験のために、該溶液に対して、0.097mmol/mlのH2O2水溶液を含有するイソプロパノール溶液0.5ml(0.09eq.)を加えた液(ブランク液)を40℃の恒温槽中、4日間放置した。
上記の各試験において、得られた(3R,5S)DOLEに含有される変性物の量を測定し表4に示した。
市販のイソプロパノール9mLに(3R,5S)DOLE240mgを溶解させた。加速安定性試験のために、該溶液に対して、0.097mmol/mlのH2O2水溶液を含有するイソプロパノール溶液0.5ml(0.09eq.)を加えた液(ブランク液)を、40℃の恒温槽中、4日間放置した(ブランク)。
一方、上記のブランク液に対して、0.0265mmol/mlチオ硫酸ナトリウム水溶液1mlを更に添加した液(チオ硫酸ナトリウム添加液)を、上記と同様に、40℃の恒温槽中、4日間放置した。
上記の各試験において、得られた(3R,5S)DOLEに含有される変性物の量を測定し表5に示した。
