摘要: 本文报导了22个6-(取代丙烯酰氨)青霉烷酸化合物的合成.这类化合物系以相应的取代丙烯酸,通过混合酸酐或酰氯,在微碱性、低温下,与6APA进行缩合;再以N-乙基六氢吡啶或N,N′-二苄基乙二胺成盐纯化精制.它们的抗菌作用正在筛选中.Abstract: Twenty-two new derivatives of 6-aminopenicillanic acid have been prepared either by the mixed carboxylic-carbonic anhydride or by the usual acyl chloride method. They were isolated and purified either as their N-ethylpiperidine or as their N, N'-dibenzyl- ethylenediamine salts. Biological evaluations of these derivatives are in progress.
