starting from Garner’s aldehyde in ten steps and 23% overall yield. A unique feature of the synthetic route is that an acyclic precursor was constructed, using diastereoselective antireductive coupling reaction of alkyne and Garner’s aldehyde as the key step, which was then cyclized in an intramolecular aldol reaction to form the valienamine skeleton. (+)-valienamine - Garner’s aldehyde - diastereoselective
