PROCEDURE

实验过程

To a solution of 3-[(trans-4-hydroxy-cyclohexyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-5-(4-oxo-cyclohex-1-enyl)-thiophene-2-carboxylic acid (30 mg, 0.065 mmol) in a 2:1 H2O-ethanol mixture (3 mL) were added O-benzylhydroxylamine hydrochloride (21 mg, 0.13 mmol) and sodium acetate (18 mg, 0.13 mmol), and the mixture was stirred at room temperature overnight. Then the mixture was extracted with CH2Cl2, organic phase was dried over Na2SO4, concentrated under reduced pressure, and purified by column chromatography on silica gel eluting with 2-15% MeOH in CH2Cl2 to give 20 mg (54%) of 5-{4-benzyloxyimino-cyclohex-1-enyl}-3-[(trans-4-hydroxy-cyclohexyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid.
