2. A compound according to claim 1, wherein the —

OR⁴ radical of the central piperidine moiety has the trans configuration.

3. A compound as claimed in claim 1 wherein L is C_3-6cycloalkyl or C_2-6alkenyl;

or L is a radical of formula (b-1), wherein each Alk is C_1-6alkanediyl, and R⁶ is hydrogen, hydroxy, cyano, amino, C_1-6alkylsulfonylamino, C_3-6cycloalkyl or Het¹, wherein Het¹ is tetrahydrofuran;

dioxolane;

dioxolane substituted with C_1-6alkyl;

tetrahydropyran;

pyridazinyl substituted with one or more substituents selected from hydroxy, halo and C_1-6alkyl;

or a radical of formula (c-1), (c-3) or (c-4) wherein R¹³ is C_1-4alkyl;

or L is a radical of formula (b-2), wherein Alk is C_1-6alkanediyl, X is O, and R⁷ is C_1-6alkyl or hydroxyC_1-6alkyl;

or L is a radical of formula (b-2), wherein Alk is C_1-6alkanediyl, R⁷ is Het² wherein Het² is pyrazinyl substituted with C_1-6alkyl, and X is NR⁸ wherein R⁸ is hydrogen or C_1-6alkyl;
