のC-20位がR-形またはS-形であるキラル化合物を提供する。
3(R)-(tert-ブチルメチルシリルオキシ)-20(S)-ホルミル-9,20-セコプレグナ- 5(E), 7(E), 10(19)-トリエン
(実施例1):
3(R)-(tert-ブチルメチルシリルオキシ)-20(S)-ホルミル-9,20-セコプレグナ-5(E),7(E),10(19)-トリエン(化合物 (1) )(800 g, 1.8 mol)のtert-ブタノール(16L)溶液に、攪拌下、KOH (155 g, 2.76 mol)を添加した。次いで、この溶液に、良好な撹拌下、40℃にて4時間酸素ガスをバブルさせた。
反応が完結した後、tert-ブタノールを蒸発させて除去し、残渣を酢酸エチル(8L)に溶解させ、水で抽出した(8L x 2回)。得られた有機相をMgSO4で無水にした後、濾過した。濾液を、減圧下で濃縮して乾燥させると、オイル状の残渣が得られ、これをカラムカラムクロマトグラフィーで精製(シリカゲル、溶離液はヘキサン中の5%酢酸エチル)して、所望の生成物である化合物(2)を523 g得た(収率67%)。
図2に、化合物(2)の1H NMRの結果を示す。
図3に、化合物(2)の13C NMRの結果を示す。
フラスコに、3(R)-(tert-ブチルメチルシリルオキシ)-20(S)-ホルミル-9,20-セコプレグナ-5(E),7(E),10(19)-トリエン (化合物 (1))(3 g, 6.78 mmol)、N,N-ジメチルホルムアミド(150 ml)、1,4-ジアザビシクロ[2.2.2]オクタン(678 mg, 6 mmol), 酢酸銅一水和物(101 mg, 0.5 mmol)、および2,2’-ビピリジル(82 mg,0.51 mmol)を加えた。この混合物を、40℃にて6日間、良好な撹拌下で空気をバブルさせた。
