    • A novel intermediate which is for use in efficiently producing a 1beta-methylcarbapenem compound for oral administration; and a process for producing the intermediate. The process, which is for producing a novel beta-lactam compound represented by the general formula (4), is characterized by reacting a beta-lactam compound represented by the general formula (5) as a starting material with a compound represented by the general formula (6) in the presence of a base to obtain a novel beta-lactam compound represented by the general formula (1), protecting the hydroxy group, subsequently cyclizing the protected compound in the presence of a strong base, reacting the cyclized compound with diphenylphosphoryl chloride to obtain a novel beta-lactam compound represented by the general formula (3), and removing the protective group therefrom. (5) (6) (1) (3) (4) (In the formulae, R1 represents trimethylsilyl or triethylsilyl; R2 represents aryl or heteroaryl; R3 represents C1-10 alkyl or C3- 10 cycloalkyl; and X represents halogeno.)
    • 一种用于口服给药的高效制备1β-甲基碳青霉烯化合物的新型中间体; 和中间体的制造方法。 用于生产由通式(4)表示的新型β-内酰胺化合物的方法的特征在于使由通式(5)表示的β-内酰胺化合物作为起始原料与通式 式(6)的化合物,得到由通式(1)表示的新型β-内酰胺化合物,保护羟基,随后在强碱存在下环化受保护的化合物,使环化的化合物与 二苯基磷酰氯,得到通式(3)表示的新型β-内酰胺化合物,除去保护基。 (5)(6)(1)(3)(4)(式中,R1表示三甲基甲硅烷基或三乙基甲硅烷基; R 2表示芳基或杂芳基; R 3表示C 1-10烷基或C 3-10环烷基; X表示卤代。
