Glutathione (GSH) has two important biological activities, GSH conjugation and radical scavenging. In this work, we determined that GSH can participate in an intramolecular cyclization between the glutamic α-carboxylic acid and the cysteinyl thiol m

Prolinamido-glycoside catalyzed asymmetric aldol reaction in aqueous media is reported. The reactions are rapid and highly stereoselective when water is used as solvent. The stereoselectivities were under influence of configurations of a prolyl resid

Prolinamido-glycosides, water-compatible organocatalysts, are capable of catalyzing the stereoselective aldol reaction in aqueous media. The aldol reaction of 2,2-dimethyl-1,3-dioxan-5-one with aldehydo sugars in the isopropylidene form gave ketoses
