Yield:-
Reaction Conditions:
in water at 80; for 8 h;Overall yield = 162.1 g;
Steps:
5.1 (1) Preparation of compounds IV, V, VI:
To a 1 L four-necked flask, 90 g (0.6 mol) of L-methionine, 79.4 g (0.84 mol) of chloroacetic acid, and 500 ml of water were added, and the mixture was stirred uniformly, and slowly heated to 80 ° C to carry out a reaction for 8 hours; After the reaction is over, recovering solvent water under reduced pressure and reduced pressure, a total of 162.1 g of a mixture of L-homoserine lactone hydrochloride, (methylthio)acetic acid and thiodiacetic acid was obtained, and the next step reaction was carried out without isolation;
