Abstract
The stereocontrolled total synthesis of (±)-halichonine B was achieved in 18 steps for the longest linear sequence. This synthesis features the stereoselective construction of a trans-fused dehydrodecalin framework containing three consecutive stereocenters through sequential intramolecular conjugate additions. Additionally, the strategic use of nitrobenzenesulfonamides enabled the efficient installation of a branched diamine moiety.
