    Synthesis and structure-activity relationships of cephalosporins with C-3' catechol-containing residues
    摘要:
    Cephalosporins with new catechol substituents at C-3' have been synthesized, including novel compounds with C-3' carbon-carbon bonds. Many of these compounds have high potency against Gram-negative bacteria, in particular against resistant strains like Pseudomonas aeruginosa. Structure-activity relationships are discussed in terms of their dependence on the pK(a) of the C-3' catechol and also in terms of steric and conformational factors of the C-3' substituent. The best overall properties were found in compounds with a bulky and/or conformationally restricted acidic C-3' catechol.

  • Some anomalous reactions of 4-quinolone-5-diazonium salts
    作者:Judit Frank、Piroska Rákóczy、Lajos Radics、Eszter Gács-Baitz

    日期:1981.8
    Diazotisation of the 5-amino function in 6,7-alkoxy-l-ethyl-l,4-dihydro-4-oxoquinoline-3-carboxylic acids led to various products. Dediazoniation was always accompanied by fission of the 6-alkoxy substituent; 6,7-methylenedioxy groups gave formaldehyde which could form a m-dioxino ring. Hydrolysis of the diazonium chlorides resulted in halo-dediazoniation.
    5-氨基官能团在6,7-烷氧基-1-乙基-1,4-二氢-4-氧代喹啉-3-羧酸中的重氮化反应产生了各种产物。脱重氮总是伴随着6-烷氧基取代基的裂变。6,7-亚甲二氧基团,得到甲醛能构成米-dioxino环。重氮氯化物的水解导致卤素脱重氮。
