Totalsynthesis of the complex polycyclic indole alkaloid (±)-communesinF has been accomplished in 23 reaction steps in about 3% overall yield. The key steps relied on a highly efficient methodology for assembling the pentacyclic substructure 2 with the C7 quaternary carbon, the stereoselective preparation of the second C8 quaternary carbon by a two-step one-pot O-allylation and consecutive 3,3-rearrangement
