A Simple Total Synthesis of the Isoindolobenzazepine Alkaloids Lennoxamine and Chilenamine

Lennoxamine (8) and chilenamine (9) have been synthesized from 3-(3,4-methylenedioxybenzylidene)-6,7-dimethoxyphthalide (1) in four and five high-yielding steps, respectively.The key step of the process is the cyclization, by intramolecular alkylation, of 3-(3,4-methylenedioxybenzyl)-6,7-dimethoxyphthalimidin-2-ylacetaldehyde dimethyl acetal (3) to 13,13a-dihydro-3,4-dimethoxy-10,11-methylenedioxyisoindolobenzazepin-5-one (7).Attempts to prepare (3) by base-catalysed cyclization of 3,4-dimethoxy-3',4'-methylenedioxystilbene-2-(2,2-dimethoxyethyl)carboxamide (15) were unsuccesful.
