    摘要: Cephem and penam compounds having a partial structure of formula (II): ##STR1## wherein R.sup.1 and R.sup.2, respectively, represent a hydrocarbon group which is attached to P, either directly or through an oxygen atom, and which may optionally be substituted, and R.sup.3 is a hydrocarbon residue, are useful as intermediates for synthetic penicillins and cephalosporins, which in turn are useful as antibiotics or intermediates for some other synthetic penicillins and cephalosporins having antibiotic activity. To the 6- or 7-amino group of these penam or cephem compounds an objective acyl group can be introduced to give 6- or 7-acyl amino compound in a good yield, without isomerization of 6.alpha.-or 7.alpha.-substituent OR.sup.3 of the penam or cephem compounds.
