摘要
A concise route for the syntheses of (+/-)-cherylline and latifine dimethyl ether is reported. The key steps involved are Michael addition of veratrole with p-methoxy nitrostyrene (for cherylline), anisole with 2,3-dimethoxy nitrostyrene (for latifine), and reduction of nitro intermediate, followed by Pictet-Spengler cyclization.
