experimental part, p. 1588 - 1594 (2010/07/04)
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.

4-Substituted 1,2,3,4-tetrahydroisoquinolin-4-ols were prepared from N-(2-iodobenzyl)phenacylamines by an intramolecular Barbier reaction with butyllithium and by an insertion reaction with zerovalent nickel. The scope and limitations of these reactions were discussed.
