摘要

Compounds of the general formula (I) IMAGE (I) (wherein X represents a halogen atom; R1 and R2 respectively represent a combination selected from the group consisting of: a hydroxy group and a hydrogen atom; a halogen atom and a hydrogen atom; and a hydrogen atom and a halogen atom; and R3 and R4, which may be the same or different, each represent a substituent selected from the group consisting of a halogen atom and a hydroxy group; at least one of R1, R2 and R3 representing a halogen atom) are potent sweeteners obtainable by opening a corresponding 3',4'-lyxoepoxide with a source of halide ions.
