The present invention relates to L-aspartyl-3-(bicycloalkyl)-L-alanine alkyl esters having high sweetness intensity, of the formula:
wherein R¹ is a substituted or an unsubstituted bicycloalkyl ring, said ring having 7 to 8 carbon atoms, the 2-position ring carbon atoms is bound to the alanine moiety, the two carbon atoms of the ring that are vicinal to the 2-position carbon are each substituted by a hydrogen or lower alkyl, the total number of alkyl groups bound to the vicinal carbons is less than three, and R² is methyl. The "2R" configuration enantiomers of the R¹ group are especially preferred. In preferred embodiments of the invention, R¹ is a bornyl, camphanyl, norbornyl, 1-methylnorbornyl, 3-methynorbornyl, 7,7-dimethylnorbornyl, bicyclo [2.2.2] octyl, or pinanyl ring. The compounds of the invention, or edible salts thereof, can be used for sweetening edible products such as foods and beverages.
本发明涉及具有高甜度的 L-天冬氨酰-3-(双环烷基)-L-丙氨酸烷基酯,其式如下:
其中,R¹为取代或未取代的双环烷基环,所述环具有 7 至 8 个碳原子,环上 2 位碳原子与丙氨酸分子结合,环上与 2 位碳相邻的两个碳原子分别被氢或低级烷基取代,与相邻碳结合的烷基总数少于 3 个,R²为甲基。特别优选 R¹ 基团的 "2R "构型对映体。在本发明的优选实施方案中,R¹是一个降冰片基、樟脑基、降冰片基、1-甲基降冰片基、3-甲基降冰片基、7,7-二甲基降冰片基、双环[2.2.2]辛基或蒎烷基环。本发明的化合物或其食用盐可用于食品和饮料等可食用产品的甜味剂。
