Disclosed is a quinoline derivative having the general formula ##STR1## where A represents a six-membered hydrocarbon ring; X represents an oxygen atom, an .dbd.NOR.sup.1 group in which R.sup.1 is a hydrogen atom or a lower alkyl radical of from 1 to 5 carbon atoms, a hydroxyl group, or an --NHR.sup.2 group in which R.sup.2 is a hydrogen atom or an acyl group; and Y represents a hydrogen atom, a salt-forming radical, or an ester-forming radical. This quinoline derivative is a novel compound which has antiallergic effects in itself and is useful as an intermediate in the production of penicillin or cephalosporin derivatives.
揭示了一种喹啉衍生物,其通式为##STR1##其中A代表一个六元环烃环;X代表一个氧原子,一个.dbd.NOR.sup.1基团,其中R.sup.1是一个氢原子或由1至5个碳原子组成的较低烷基基团,一个羟基,或一个--NHR.sup.2基团,其中R.sup.2是一个氢原子或一个酰基基团;Y代表一个氢原子,一个形成盐的基团,或一个形成酯的基团。这种喹啉衍生物是一种新颖的化合物,具有抗过敏作用,并可用作生产青霉素或头孢菌素衍生物的中间体。
