  • Anhydropenicillin: a key intermediate for the stereocontrolled introduction of the 6-<i>R</i>-hydroxyethyl side chain of the penem and carbapenem antibiotics
    作者:Alain Martel、Jean-Paul Daris、Carol Bachand、Marcel Menard
    DOI:10.1139/v87-364
    日期:1987.9.1

    Aldol condensation of the magnesium enolate derived from anhydro-6,6-dibromopenicillin with acetaldehyde allows for the stereospecific introduction of a 1-R-hydroxyethyl substituent at C-6. Protection of the hydroxy group followed by reductive dehalogenation provides anhydro-6(α)-[(1-R)-(tert;-butyldimethylsilyloxy)-ethyl]-penicillin, an intermediate in the synthesis of thienamycin. A high yield conversion of this anhydro derivative to (4-R)-acetoxy-(3-S)-[(1-R)-(tert-butyldimethylsilyloxy-ethyl]-azetidin-2-one (5) is also reported.

    醇酸盐与乙醛的Aldol缩合反应,使得从无6,6-二青霉素得到的醇酸盐在C-6位置特异性引入1-R-羟乙基取代基。羟基的保护后进行还原去卤反应,得到无6(α)-[(1-R)-(tert;-butyldimethylsilyloxy)-ethyl]-青霉素,这是合成噻霉素的中间体。报道了将这种无生物高产率转化为(4-R)-乙酰基-(3-S)-[(1-R)-(tert-butyldimethylsilyloxy-ethyl]-氮杂环丙烷-2- (5) 的方法。

    The 4-chloroazetidinone 10, a very reactive chiral intermediate for 1-β-methylcarbapenems (1b), was easily prepared and isolated as a solid crystalline compound from the corresponding sulfide 5. Another chiral intermediate (16d) bearing the 1-β-methyl moiety was prepared by stereoselective aldol type condensation of either azetidinone 4 or 10 with metal enolates 14 (R = S—Bu′, M = ZrCp2Cl, [Formula: see text], and SnBr). The β/α ratios were 9:1, 3:1, 2:1 respectively.

    4-吡嗪10是1-β-甲基卡巴比林(1b)的非常活性手性中间体,可以从相应的醚5中轻松制备并分离为固体结晶化合物。另一个携带1-β-甲基基团的手性中间体(16d)是通过对吡嗪4或10与醇酸盐14(R = S—Bu',M = ZrCp2Cl,[Formula: see text]和SnBr)的立体选择性醛缩反应制备的。β/α比例分别为9:1,3:1,2:1。
