Acetyl chloride → S-Acetylglutathione

Participants

Reaction Steps

Using in the procedure of Example 1 acetyl chloride, in place of pivaloyl chloride, L-glutathione reduced (15.4 g) provides, after usual work-up, a crude white solid which is dissolved in warm acetone/water (2/1; 40° C.; 300 ml). The obtained solution is further diluted with more acetone (100 ml) and cooled on ice-water bath. After about two hours the white crystalline precipitate is collected, washed with the solvent (40 ml) and dried under vacuum affording γ-L-glutamyl-S-acetyl-L-cysteinyl-glycine (14.8 g yield=85%)
