摘要
The first total synthesis of the tetracyclic alkaloid (-)-acutumine is described. Key reactions include an asymmetric ketone allylation mediated by Nakamura's chiral allylzinc reagent, an anionic oxy-Cope rearrangement, and the Lewis acid-promoted cyclization of an amine onto an alpha,beta-unsaturated dimethyl ketal.
