  • Patent number: 5801242
    Abstract: The present invention provides processes for making compounds of the structure(Q--L.sup.1)--L--(L.sup.2 --B)wherein(I) Q is a quinolone moiety;(II) B is a lactam moiety; and(III) L, L.sup.1, and L.sup.2 together comprise a linking moiety;comprising the steps of:(1) coupling a compound of Formula (III) with a lactam-containing compound to form an intermediate compound; and(2) cyclizing the intermediate by reaction with an organosilicon compound to give a compound of the formula (Q--L.sup.1)--L--(L.sup.2 --B).Preferably, the process additionally comprises a step prior to the coupling step, wherein protected forms of the compound of Formula (III) and the lactam compound are formed; and deprotection steps after the cyclization step, wherein the protecting groups are removed. Preferred antimicrobial compounds made by these processes are those where the beta-lactam moiety is a penem, a carbapenem, a cephem, or a carbacephem. Also preferred are those compounds where L.sup.1, L, and L.sup.
