The 3-substituted 2,4,6-trihalogenated benzamides having the formula I ##STR1## wherein Hal is chlorine, bromine, or iodine and Z is a carboxyl group or the group ##STR2## wherein P is 1 and L is 0 or 1, with the proviso that L is 0 when K is 0; K is 0, 2, 3, or 4; M is 0, 1, 2 or 3; N is 0 or 1; X is a hydrogen atom; Y is a hydrogen atom or a lower alkyl group of 1-4 carbon atoms, or when either M or N is other than 0, a hydroxy group, a C.sub.1-6 alkoxy group or a C.sub.1-4 acyloxy group, or when N is 1 and M is other than 0, X and Y together represent an additional carbon-carbon bond; or P and L are each 0; p1 K is 0, 2, 3 or 4; M is 0, 1, 2 or 3; N is 0 or 1; X is a hydrogen atom; Y is a hydrogen atom, a lower alkyl group of 1-4 carbon atoms, a hydroxy group, a C.sub.1-6 alkoxy group, a C.sub.1-4 acyloxy group or, when N is 1, X and Y together represent an additional carbon-carbon bond; and salts thereof with inorganic bases, exhibit an extraordinarily high sweetening power and are excellent substitutes for natural sweetening agents.
公式I的化合物为3-取代的2,4,6-三卤代苯甲酰胺,其中Hal为氯、溴或碘,Z为羧基或基团##STR2##其中P为1,L为0或1,但当K为0时,L为0;K为0、2、3或4;M为0、1、2或3;N为0或1;X为氢原子;Y为氢原子或1-4碳原子的低级烷基,或当M或N不为0时,为羟基、C.sub.1-6烷氧基或C.sub.1-4酰氧基,或当N为1且M不为0时,X和Y共同表示额外的碳-碳键;或P和L均为0;p1 K为0、2、3或4;M为0、1、2或3;N为0或1;X为氢原子;Y为氢原子、1-4碳原子的低级烷基、羟基、C.sub.1-6烷氧基、C.sub.1-4酰氧基或当N为1时,X和Y共同表示额外的碳-碳键;以及它们与无机碱的盐,具有非常高的甜味能力,是天然甜味剂的优秀替代品。
