methyl (2S)-2-[(2-methylpropan-2-yl)oxycarbonylamino]-3-sulfanylpropanoate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Diisopropylethylamine (3.38 mL, 19.4 mmol) was added to a solution of methyl N-(tert-butoxycarbonyl)-D-cysteinate (3.04 g, 12.9 mmol) and □-trans-nitrostyrene (1.93 g, 12.92 mmol) in acetonitrile (80 mL). After 15 min, the reaction was concentrated. Purification by silica gel chromatography (100% hexanes→30% ethyl acetate/hexanes) gave the title compound (4.52 g). the reaction was concentrated Purification by silica gel chromatography (100% hexanes→30% ethyl acetate/hexanes)
