Penem compounds are of the formule:
where R1 is H or hydroxyethyl, wherein the -OH may be protected
R2 is H or a protective group, e.g. alkoxycarbonyl;
R3 is H or a protective group, e.g. alkyl;
X is methylene or alkyl-methylene or S;
Y is amino (-NH2) which may be substituted by various groups which can form a ring.
Synthesis is from a B-lactam derivative wherein the 2-position has a reactive ester alcohol group or alkylsulfinyl group, reacted with a pyrrolidinyl derivative in a solvent in presence of a base.
The compounds are useful as antimicrobial agents.
培南化合物的形式如下
其中 R1 是 H 或羟乙基,其中 -OH 可以是受保护的
R2 是 H 或保护基,如烷氧羰基;
R3 是 H 或保护基,如烷基;
X 是亚甲基或烷基亚甲基或 S;
Y 是氨基(-NH2),可被各种基团取代,形成一个环。
合成方法是将 B-内酰胺衍生物(其中 2 位具有活性酯醇基或烷基亚磺酰基)与吡咯烷衍生物在溶剂中并在碱存在下进行反应。
这些化合物可用作抗菌剂。
