Abstract
Description
本発明は、グリコペプチド抗生物質の誘導体を調製する新規方法に関する。さらに具体的には、本発明は、アミノ含有側鎖を有するグリコペプチド抗生物質の誘導体を調製する多段方法に関し、その工程は、中間体反応生成物を単離することなく、単一反応容器内で行われる。
グリコペプチド(例えば、ダルバヘプチド)は、種々の微生物から産生される周知の種類の抗生物質である(Glycopeptide Antibiotics,R.Nagarajan編、Marcel Dekker,Inc.New York(1994)を参照)。このようなグリコペプチドの多くの合成誘導体もまた、当該技術分野で公知であり、それらの誘導体は、典型的には、天然に生じるグリコペプチドと比べて、特性が向上している(高い抗菌活性を含めて)と報告されている。例えば、2000年7月6日に公開されたWO00/39156は、ヘテロ原子含有側鎖を有する種々のグリコペプチド誘導体を記述しており、これには、アミノ含有側鎖を有する誘導体が含まれる。これらのアミノ含有側鎖誘導体は、抗生物質として、また、さらなるグリコペプチド誘導体を生成する中間体として、特に有用である。
本発明は、アミノ含有側鎖を有するグリコペプチド抗生物質の誘導体を調製する新規方法を提供する。他にも利点はあるが、本発明は、中間体反応生成物を単離することなく、単一反応容器内で行われ、それにより、以前の方法と比較して、その方法の無駄が少なくなり、全体的な効率および収率が改善される。

(d)工程(c)から得た反応混合物をアミンと接触させて、式Iの化合物またはその塩を得る工程。

ここで、Wは、9−フルオレニルメチル、3−インデニルメチル、ベンズ[f]インデン−3−イルメチル、17−テトラベンゾ[a,c,g,i]フルオレニルメチル、2,7−ジ−第三級ブチル[9−(10,10−ジオキソ−10,10,10,10−テトラヒドロチオキサンチル)]メチル、1,1−ジオキソベンゾ[b]チオフェン−2−イルメチルからなる群から選択され、ここで、該9−フルオレニルメチル基は、必要に応じて、C1〜6アルキル、ハロ、ニトロおよびスルホからなる群から選択される1個〜3個の置換基で置換されている。
本発明は、アミノ含有側鎖を有するグリコペプチド誘導体を調製する新規方法に関する。このような方法を説明するとき、以下の用語は、特に明記しない限り、以下の意味を有する。

(N−Fmoc−デシルアミノアセトアルデヒドの調製)
(工程A − N−Fmoc−2−(n−デシルアミノ)エタノールの調製)
2−(n−デシルアミノ)エタノール(2.3g、11mmol、1.1eq)およびDIPEA(2.0mL、11mmol、1.1eq)を塩化メチレン(15mL)に溶解し、そして氷浴で冷却した。塩化メチレン(15ml)中の9−フルオレニルメチルクロロホルメート(2.6g、10mmol、1.0eq)を加え、その混合物を30分間攪拌し、次いで、3N塩酸(50mL)で2回洗浄し、そして飽和炭酸水素ナトリウム(50mL)で洗浄した。その有機物を硫酸マグネシウムで乾燥し、減圧下にて、溶媒を除去した。N−Fmoc−2−(n−デシルアミノ)エタノール(4.6g、11mmol、108%)は、さらに精製することなく、使用した。
塩化オキサリル(12.24mL)および塩化メチレン(50mL)の溶液に、−35〜−45℃で、20分間にわたって、塩化メチレン(25mL)中のDMSO(14.75g)を加えた。その反応混合物を、−35〜−45℃で、10分間攪拌した。N−Fmoc−2−(n−デシルアミノ)エタノール(20.0g)の塩化メチレン(70mL)溶液を25分間にわたって加え、次いで、−35〜−45℃で、40分間攪拌した。次いで、トリエチルアミン(21.49g)を加え、その混合物を、−10〜−20℃で、30分間攪拌した。この反応混合物を、その内部温度を0〜5℃で維持しつつ、水(120mL)に続いて濃硫酸(20.0g)でクエンチした。その有機層を単離し、そして2%硫酸(100mL)に続いて水(2×100mL)で洗浄した。この有機溶液を、減圧下にて、60℃で、約100mLまで蒸留した。ヘプタン(100mL)を加え、その油浴の温度を80℃まで上げ、残留容量が100mLになるまで、その蒸留を継続した。さらに多くのヘプタン(100mL)を加え、その蒸留を100mLの容量まで繰り返した。加熱浴を、15℃の冷水浴と交換した。この浴を、20分間にわたって、5℃までゆっくりと冷却すると、その生成物の沈殿が開始した。次いで、そのスラリーを−5℃〜−10℃まで冷却し、そしてこのスラリーを2時間攪拌した。次いで、ブフナー漏斗上で固形物を集め、そして冷(−5℃)ヘプタン(2×15mL)で洗浄した。その湿潤固形物を減圧して乾燥し、表題アルデヒドを得た。
(Nvan−2−(n−デシルアミノ)エチルバンコマイシン塩酸塩の調製)
バンコマイシン塩酸塩20g(13.46mmol)およびN−Fmoc−2−(n−デシルアミノ)アセトアルデヒド6.526g(15.48mmol)の攪拌混合物に、N,N−ジメチルホルムアミド130mLおよびN,N−ジイソプロピルエチルアミン4.7mL(26.92mmol)を加えた。得られた混合物を、窒素下にて、室温で、15時間攪拌し、0℃で、メタノール75mLおよびトリフルオロ酢酸4.15mL(53.84mmol)を連続して加えた。この混合物を1時間攪拌し、そしてボラン−ピリジン錯体1.93mL(15.48mmol)を加えた。得られた混合物を、0℃で、4時間攪拌し、そしてメタノール中の2Mメチルアミン80mL(161.52mmol)を加えた。得られた混合物を室温まで暖め、そして50時間攪拌し、0℃まで冷却し、そして水(350mL)を滴下した。その混合物を、濃塩酸11mLをゆっくり加えることにより、pH3.60まで酸性化すると、沈殿が生じた。この混合物を、さらに30分間攪拌し、次いで、ブフナー漏斗で濾過した。得られた湿潤ケークを水(2×200mL)で洗浄し、そして16時間減圧乾燥して、粗Nvan−2−(n−デシルアミノ)エチルバンコマイシン塩酸塩9.8gを得た。
