    摘要: There is described a process for the manufacture of a compound of the formula ##STR1## wherein R.sup.1 is lower alkyl, lower alkanoyl, lower alkenyl or the group --CH.sub.2 COOR.sup.2 or --C(CH.sub.3).sub.2 COOR.sup.2 and R.sup.2 is a readily cleavable group, by reacting a compound of the formula ##STR2## wherein R is lower alkyl, with an alkali metal allylate and reacting the resulting compound of the formula ##STR3## wherein M is an alkali metal atom, with a compound of the formula R.sup.1 -X, wherein X is a leaving group. This process can be used to manufacture antimicrobially active mono-.beta.-lactam, cephalosporin and penicillin derivatives.
