<p>A 4-acyloxyquinoline derivative represented by the general formula (I): <CHEM> wherein R<1> represents a hydrogen atom, a C1-C18 alkyl, C2-C18 alkenyl, C3-C10 cycloalkyl which may be optionally substituted, phenylloweralkyl, phenoxyloweralkyl, aryl group, a group OR<4>, where R<4> represents a lower alkyl or aryl group, or a grou p <CHEM> where X represents an oxygen or a sulphur atom; R<2> represents a hydrogen atom, a lower alkyl group or a group -COOR<5> where R<5> represents a hydrogen atom or a lower alkyl group; R<3> represents a hydrogen atom, a C1-C10 alkyl or C2-C10 alkenyl group, provided that R<1> does not represent OR<4> when R<2> is a hydrogen atom and R<3> is methyl; R<2> and R<3> together represent a group (CH2)m, wherein m is 3 or 4, and W represents a hydrogen atom, 1 to 4 halogen atoms, a lower alkyl or lower alkoxy group which may be the same or different and with which the left-hand nucleus is substituted, provided that the compound wherein R<1> represents methyl, R<2> , R<3> and W each represent a hydrogen atom is excluded.</p> |
