Neuroactive metabolites from the bark of Galbulimima belgraveana occur in variable distribution among trees and are not easily procured by chemical synthesis due to elaborate bond networks and dense stereochemistry. Previous syntheses of complex congeners like himgaline have relied on iterative, stepwise installation of multiple methine stereocenters. Here we decrease the synthetic burden of himgaline to nearly one-third of the prior best (7–9 vs. 19–31 steps) by cross-coupling high fraction aromatic (FAr) building blocks followed by complete, stereoselective reduction to high-fraction sp3 () products. This short entry into GB alkaloid space allows its extensive exploration and biological interrogation. Aromatic building blocks are merged and reduced stereoselectively to yield surprising syntheses of complex plant metabolites.
