Alitame is an intense sweetener, with sweetness potency 2000 times greater than that of sucrose. Alitame is prepared by a multistep synthesis involving the reaction between two intermediates, (S)-[2,5-dioxo-(4-thiazolidine)] acetic acid and (R)-2-amino-N-(2,2,4,4-tetramethyl-3-thietanyl) propanamide.
The final product is isolated and purified through crystallization of an alitame-4-methylbenzenesulfonic acid molecules, followed by additional purification steps, and finally recrystallization from water.
