ASPARTYL DIPEPTIDE ESTER DERIVATIVES AND SWEETENERS

摘要

Novel aspartyl dipeptide ester derivatives (including those in the form of a salt) having an excellent sweetening effect and usable as sweeteners such as N- [N-[3-(3-methyl-4-hydoxyphenyl)propyl]-L-.alpha.-aspartyl]-L-phenylala nine 1 - methyl ester and N-[N-[3-(3-hydroxy-4-methoxyphenyl)propyl]-L-.alpha.- aspartyl]-L-phenylalanine 1-methyl ester; and excellent sweeteners, etc. containing these novel derivatives. Thus, it becomes possible to provide low - caloric sweeteners which are superior particularly in degree of sweetness to the conventional ones.
