stereochemistry remains an unsolved issue in the synthesis of eburnane‐type indole alkaloids. Provided herein is a simple solution to this problem by developing a unified and diastereoselective synthesis of four representative members of this class of natural products, namely, eburnamonine, larutensine, terengganensine B, and melokhanine E. The synthesis features the following key steps: a) an α‐iminol

Short syntheses are described for the (+/-)-forms of the recently isolated eburnane type alkaloids (-)-ebumaminol [(-)-1] and (+)-larutensine [(+)-2], and for the not yet naturally found 18-hydroxyebumamonine (3) and 16-epieburnaminol (4).
