PROCEDURE

实验过程

A mixture of 1-(3,4-dimethoxyphenyl)-2-nitro-6-cyano-6-(i-propyl)-6-(3,4-dimethoxyphenyl)hexan-3-ol (8, 75 g, 0.154 mol), 4-dimethylaminopyridine ("DMAP," 1.5 g, Aldrich), and acetic anhydride (23 mL) in CH2Cl2 (700 mL) was heated at reflux for 40 minutes to yield 1-(3,4-dimethoxyphenyl)-2-nitro-3-acetoxy-6-cyano-6-(i-propyl)-6-(3,4-dimethoxyphenyl)hexane (9), which was used in the next step without isolation.
