Participants

Reaction Steps

To 3-(1,2,3,4-tetrahydro-1-oxo-isoquinoline-2-yl)-acetamino-5-benzenesulfonylamino-4-hydroxy-pentanoic acid, tert-butyl ester (0.9 g, 1.7 mMol) in 20 mL of dichloromethane was added 1.1.1-triacetoxy-1.1-dihydro-1.2-benziodoxol-3-(1H)-one (Dess Martin periodinane, 1.08 g, 2.5 mMol). After 2 hours at room temperature the reaction mixture was diluted with ether, filtered, washed with sodium hydrogen carbonate and water, dried over sodium sulfate, and concentrated under reduced pressure. Chromatography over silica (elution with dichloromethane/methanol 15:1) gave 3-(1,2,3,4-tetrahydro-1-oxo-isoquinoline-2-yl)-acetamino-5-benzenesulfonylamino-4-oxo-pentanoic acid, tert-butyl ester (0.45 g).
