    摘要: Disclosed is a process for preparing a .beta.-lactam compound represented by the formula: ##STR1## wherein R.sup.1 represents a hydroxy-substituted lower alkyl group or an amino group each of which may be protected; R.sup.2 represents hydrogen atom or an ester residue; X represents a methylene group which may be substituted by a lower alkyl group, sulfur atom or a group represented by the formula: --A--CH.sub.2 -- where A represents sulfur atom, oxygen atom or methylene group; and W represents an active ester residue of hydroxyl group, or a salt thereof, which comprises the steps of treating a 1-aza-3-thia-bicycloalkane compound represented by the formula: ##STR2## wherein R.sup.1, R.sup.2 and X have the same meanings as defined above, or a salt thereof with a base in the presence of a desulfurizing agent and then reacting the resulting compound with an active esterifying agent of hydroxyl group.
