Synthesis of a N-Boc-protected piperidin-2-yl phosphine oxide starting from piperidine in three steps, followed by olefination using a variety of α,β-unsaturated aldehydes resulted in tert-butyl 2-(2′- alkenylidene)piperidine-1-carboxylates in high yields

Both enantiomers of 2-(2-propenyl)piperidine 1 (76-88% ee), prepared via the first asymmetric dihydroxylation (AD) of 5-hexenyl azide, underwent the second AD to provide all four of the stereoisomeric 2-(2,3- dihydroxypropyl)piperidines 2 with enantiomeric enhancement.(>98% ee). An asymmetric synthesis, starting from 2, of several 2-(2- hydroxyalkyl)piperidine alkaloids [(-)halosaline, (+)-N-methylallosedridine, (+)-8-ethylnorlobelol, (+)-sedridine, (+)-allosedridine, (-)allosedridine, and (+)-N-methylsedridine] and the ant defense alkaloids [(+)-tetraponerine-3 (T-3), T-4, T-7, and T-8] is demonstrated.
