Efficient Syntheses of (±)-Cherylline and Latifine Dimethyl Ether
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.
A concise route for the synthesis of 4-aryltetrahydroisoquinolines was developed using the addition of Grignard reagents to nitrostyrene derivatives as the key step. The application to the synthesis of cherylline was described.

An efficient synthesis of (+/-) cherylline dimethyl ether
A concise route for the synthesis of (+/-) cherylline dimethyl ether is reported. The key steps involved are Grignard reaction, conversion of alcohol to nitrile using (N-(p-toluene sulfonyl)imidazole and sodium cyanide), reduction of the nitrile intermediate followed by Pictet–Spengler cyclisation and reductive N-methylation in a single step to provide cherylline dimethyl ether as a racemate.
