摘要：
A 2-substituted cephem derivative represented by the formula ##STR1## wherein R.sup.1 represents a substituted or unsubstituted phenyl group, substituted or unsubstituted phenylmethyl group or substituted or unsubstituted phenoxymethyl group, R.sup.2 represents hydrogen atom or protective group for carboxylic acid and Y represents allyloxy group, benzyloxy group, alkylthio group, carboxyalkylthio group or group of the formula ##STR2## wherein R.sup.4 represents hydrogen atom or lower alkyl group, X represents --O--, --S-- or ##STR3## R.sup.5 represents hydrogen atom, a lower alkyl group or phenyl group and R.sup.6 represents hydrogen atom or lower alkyl group, and a process for preparing the derivatives.
