1,1'-Thiocarbonyldiimidazole → HCID 9952107, compound

Participants

Reaction Steps

To a solution of N-[2-(4-methoxybenzylthio)-2-methylpropyl]L-cysteine methyl ester (5.0 g) in chloroform (90ml), thiocarbonyldiimidazole (3.0 g) was added and the mixture was stirred for 1.5 hr at room temperature. The reaction mixture was washed with 3N hydrochloric acid, water and then saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated in vacuo. The oily residue was purified by a silica gel column chromatography to give 5.10 g(91%) of (4R)-3-[2-(4-methoxy-benzylthio)-2-methylpropyl]-4-methoxycarbonylthiazolidine-2-thion
