摘要:
An amino acid compound of the formula: ##STR1## wherein R is a lower alkyl group, R.sub.1 is a hydrogen atom or a protecting group for carboxyl, R.sub.2 is a hydrogen atom, a protecting group for amino, an optionally substituted allyl group of the formula: ##STR2## (wherein R.sub.3 and R.sub.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.sub.2 SR.sub.5(wherein R.sub.5 is an aryl group or an ar(lower)alkyl group), which is a useful intermediate in the synthesis of 1-alkylcarbapenem compounds.
