    摘要: Described are amino acid compounds of the formula:

    wherein R is a lower alkyl group, R, is a hydrogen atom or a protecting group for carboxyl, R 2 is a hydrogen atom, a protecting group for amino, an optionally substituted allyl group of the formula:
    (wherein R 3 and R 4 are each a hydrogen atom, a lower alkyl group or an aryl group), a beta-hydroxyethyl group in which the hydroxyl group is optionally protected, a formylmethyl group in which the formyl group is optionally protected, a carboxymethyl group in which the carboxyl group is protected or a 2-furylmethyl group and X is an optionally protected carboxyl group, a hydroxymethyl group in which the hydroxyl group is optionally protected or a substituted mercaptomethyl group of the formula: -CH 2 SR 5 (wherein R s is an aryl group or an ar(lower)alkyl group), which are useful intermediates in the synthesis of 1-alkylcarbapenem compounds.
