    摘要: A novel intermediate which is for use in efficiently producing a 1β-methylcarbapenem compound for oral administration; and a process for producing the intermediate. The process, which is for producing a novel β-lactam compound represented by the general formula (4), is characterized by reacting a β-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 β-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 β-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.)

    摘要: Compounds of formula (Ia):
    in which: R 1 represents a hydrogen atom or a hydroxy-protecting group; R 2 represents a methyl group; R 3 represents a phenyl group which has a 2-substituent of formula -CYNR 5 R 6 and no further substituent or has one alkyl substituent, wherein Y represents an oxygen or sulphur atom, and R 5 and R 6 are the same or different and each represents an alkyl group, an aryl group, or R 5 and R 6 together with the nitrogen atom to which they are attached form a heterocyclic group; R 4 represents a hydrogen atom or an amino-protecting group; and Z represents a sulphur atom or an oxygen atom,
    are valuable intermediates in the preparation of carbapenem compounds and retain a desirable configuration during conversion to such carbapenem compounds.
