PROCEDURE

实验过程

To a solution of 5-(4,4-dimethyl-cyclohex-1-enyl)-3-[(trans-4-methyl-cyclohexanecarbonyl)-(4-oxo-cyclohexyl)-amino]-thiophene-2-carboxylic acid methyl ester (13.3 g, previous reaction) in 195 mL of MeOH at 0° C. was added NaBH4 (450 mg, 11.9 mmol) portion wise. The reaction mixture was stirred for 1 hour at 0° C. After completion of the reaction, HCl (1N) was slowly added. The mixture was evaporated to dryness and the residue partitioned in EtOAc and water. The water phase was extracted (3×) and the combined organic phase was washed with brine, dried over Na2SO4 and evaporated to dryness. The residue was purified by silica gel column chromatography using (30:70) EtOAc:hexane as eluent to obtain 5-(4,4-dimethyl-cyclohex-1-enyl)-3-[(trans-4-hydroxy-cyclohexyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (5155 mg) as a solid and 5-(4,4-dimethyl-cyclohex-1-enyl)-3-[(cis-4-hydroxy-cyclohexyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (789 mg) as a solid. The overall yield for steps III, IV and V was 51%.
