titleOfInvention | Process for the preparation of (subtituted)-2- carbamoyloxymethylpenam and (substituted)-3- carbamoyloxycepham |
abstract | ABSTRACT Penicillin sulfoxide esters are reacted with an iso-cyanate to produce the corresponding (substituted)-2-carbamoyl-oxymethylpenam, The corresponding (substituted)-3-carbamoyl-oxycepham or the corresponding 3-methylcephem. The 6- or 7-side-chain of these products may be cleaved to give the corresponding 6-amino (penams) or 7-amino (cephams and cephems) compounds, and the latter may be reacylated to produce different 6-acyl-2-carbamoyloxymethyl penams, 7-acyl-3-carbamoyloxy cephams and 7-acyl-3-mothylcephams. The substituent groups may be removed from the (substituted)-2-carbamoyloxypenams or the (substituted)-3-carbamoyloxycephams to give the corresponding free 2-carbamoyloxymethylpenams or 3-carbamoyloxycephams, respectively. Novel penams and cephams provided by the present invention (after removal of the carboxyl-protecting group to produce the free acid) are active against various Gram-positive and Gram-negative organisms and, accordingly, are useful antibacterial agents for the treatment of diseases caused by such organisms in animals, including man. |
