摘要:
A process for producing 2-azetidinone derivatives represented by formula ##STR1## wherein R.sup.1 denotes a protecting group of a hydroxyl group,Z denotes a hydrogen atom or a protecting group of an amino group, andQ denotes ##STR2## in which X denotes a halogen atom, Y denotes a halogen atom or OR.sup.2, R.sup.2 denotes a hydrogen atom or a protecting group of a carboxyl group, and Y.sup.2 denotes OR.sup.3 or SR.sup.4 in which R.sup.3 denotes a hydrogen atom, a protecting group of a carboxyl group or an ester residue and R.sup.4 denotes an ester residue.
