    摘要: Compounds of the general formula: ##STR1## (in which X represents a hydrogen atom or an alkoxy or arylalkoxy group) are new compounds; those where X represents a hydrogen atom or a methoxy group are potent sweeteners while those with a cleavable 6-ether group are key intermediates in the preparation of 4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose (TGS). They are prepared by chlorinating a sucrose 6-ether, by etherifying a suitably protected derivative of TGS or, in the case where X represents hydrogen, by debromination of 6-bromo-4,1',6'-trichloro-4,6,1',6'-tetradeoxygalactosucrose.
