Participants

Reaction Steps

N4-[(1S)-2-((1S)-1-[(benzyloxy)methyl]-2-hydroxy-3-oxo-3-[(1,1,3,3-tetramethyl butyl)amino]propylamino)-1-(cyclohexylmethyl)-2-oxoethyl]-4-Morpholinecarboxamide (260 mg, 0.4 mmole) was dissolved in CH2Cl2 (4 mL). Dess-Martin periodinane (550 mg, 1.2 mmole) was added. The solution was stirred for 2 h at room temperature and quenched with Na2S2O3 and saturated bicarbonate solution. After extracting with CH2Cl2, the organic layer was dried over MgSO4, filtered, and concentrated by rotary evaporation. Purification by chromatography (silica, 1/3: Hexane/EtOAc, Rf=0.6) afforded N4-[(1S)-2-((1S)-1-[(benzyloxy)methyl]-2,3-dioxo-3-[(1,1,3,3-tetramethylbutyl)amino]propylamino)-1-(cyclohexyl-methyl)-2-oxoethyl]-4-morpholinecarboxamide as a white solid (170 mg, 71%).
