3,3-Dimethylbutanal → Neotame

참여 물질

반응 단계

3,3-Dimethylbutyraldehyde and the acid salt of aspartame or the N-protected aspartame are reacted for a time and at a temperature sufficient to produce neotame. Generally, the time ranges from about 1 to about 24 hours, preferably from about 2 to about 4 hours after addition of the 3,3-dimethylbutyraldehyde is complete. If the 3,3-dimethylbutyraldehyde is added to the reaction mixture all at once, then the time sufficient to produce neotame preferably ranges from about 6 to about 24 hours. Generally, the temperature sufficient to produce neotame according to the present invention ranges from about 20° C. to about 60° C., preferably from about 22° C. to about 40° C.
