Efficient and Selective Syntheses of S-Acyl and N-Acyl Glutathiones

[摘要]：Selective syntheses of S-acyl glutathiones are achieved in 79-98% yields using 1-acyl-1H-benzotriazoles in the presence of potassium bicarbonate in aqueous methanol at 20 degrees C. N-Acylation of S-(p-nitrobenzoyl) glutathione with 1-acyl-1H-benzotriazoles followed by deprotection of the p-nitrobenzoyl groups under mild conditions gave 63-78% yields of N-acyl glutathiones. These methodologies should be useful for the S-acylation and N-acylation of peptides and glycopeptides.
