摘要

Multistep synthesis (12 steps) of new pentacyclic compounds, which are structurally very close to natural marine alkaloids, was performed via a Diels–Alder reaction between 4- methylene-5-(bromomethylene)-4, 5-dihydrothiazole and a protected dioxotryptamine, itself obtained from the commercially available 2, 5-dimethoxybenzaldehyde.
