The 11-amino-azaelliptitoxin analog (11R,11aS,5R)-15 has been prepared stereoselectively in eight steps and 24 % overall yield from commercially available (S)-glycidol (7) via the original enantiopure chiral α-amino aldehyde 9, used as chiral precursor for the creation of the two other stereogenic centers of the target framework.
