摘要

The use of the dimethylphosphinothioyl (Mpt) group for the protection of the thiol function in the cysteine side-chain was studied. N, S-Bis (Mpt)-L-cysteine was obtained directly by means of a Schotten-Baumann-type reaction of Mpt–Cl with L-cysteine. The S–Mpt group was stable under acidic conditions, except for HBr in acetic acid, and it could be removed by treatment with AgNO 3 or Hg (OAc) 2 in an aqueous medium. Glutathione was ...
