    • A first embodiment of the security apparatus comprises a retaining collar; a plurality of segments forming a generally frusta-conical enclosure, with one or more of the segments having an access opening therein; and a lockable access door covering the opening. The retaining collar is separable into portions that conforms to the shape of the periphery and are coupled together around the structure. The segments have an upper portion that attaches to the collar; and have a bottom portion that extends radically downwardly from the collar at an angle of about 30 degree; with the radial edges interconnected forming the enclosure.A second embodiment of the apparatus secures a ladder supported on a wall and a retaining bar; a plurality of segments forming a generally semi-frusta-conical enclosure, with one or more of the segments having an access opening therein, and a lockable access door covering the opening.

    • The present invention provides methods of 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 beta-lactam moiety;(III) L, L.sup.1, and L.sup.2 together comprise a carbamate-containing linking moietycomprising the steps of:(1) Reacting a lactam compound of the formula B-L.sup.4 -H with phosgene to form an intermediate compound of the formula B--L.sup.4 --C(=O)--Cl, where L.sup.4 is oxygen; and(2) Coupling said intermediate compound with a quinolone compound of the formula Q-L.sup.3 -R.sup.44 ; wherein L.sup.3 is nitrogen; R.sup.44 is hydrogen, Si(R.sup.45).sub.3, or Sn(R.sup.45).sub.3 ; and R.sup.45 is lower alkyl.Preferably, the process additionally comprises steps prior to the reacting and coupling steps where esters of the lactam and quinolone compounds are made. Also preferably, the coupling step comprises adding a solution containing the quinolone compound to a solution containing the intermediate compound. The process steps are also preferably performed at a temperature of from about -80.degree. C. to about 0.degree. C. Preferred antimicrobial compounds made by these processes are those where the beta-lactam moiety is a penem.
    • 本发明提供了制备[Q-L1] -L- [L2-B [其中(I)Q为喹诺酮部分的结构的化合物的方法。 (II)B是β-内酰胺部分; (III)L,L1和L2一起包含含氨基甲酸酯的连接部分,包括以下步骤:(1)用光气反应式B-L4-H的内酰胺化合物以形成式B-L4的中间体化合物 -C(= O)-Cl,其中L4是氧; 和(2)将所述中间体化合物与式Q-L3-R44的喹诺酮化合物偶联; 其中L3是氮; R44是氢,Si(R45)3或Sn(R45)3; R 45为低级烷基。 优选地,该方法还包括在制备内酰胺和喹诺酮化合物的酯的反应和偶联步骤之前的步骤。 还优选地,偶联步骤包括将含有喹诺酮化合物的溶液加入到含有中间体化合物的溶液中。 方法步骤还优选在约-80℃至约0℃的温度下进行。通过这些方法制备的优选的抗微生物化合物是其中β-内酰胺部分是青霉烯的那些。
