Reported herein is a method for the efficient syntheses of optically active 1-alkyl homoallylic amines in yields up to 95%, 13.5:1 dr, and 98% ee under mild, aqueous reaction conditions, via the Rh-catalyzed asymmetric allylation of aliphatic aldimines. This method provides a streamlined synthetic platform for the preparation of indolizidine and piperidine alkaloids, thus demonstrating its usefulness.

An intramolecular organocatalytic enantioselective aza-Michael reaction of carbamates, sulfonamides and acetamides to α,β-unsaturated ketones was developed. This process is promoted by 9-amino-9-deoxy-epi-quinine and diphenyl hydrogen phosphate to afford
Straightforward access to enantioenriched 2-allylpiperidine: Application to the synthesis of alkaloids
Bosque, Irene,González-Gómez, José C.,Foubelo, Francisco,Yus, Miguel
experimental part, p. 780 - 784 (2012/03/26)
An efficient stereocontrolled preparation of (2R,RS)-2-allyl-(N- tert-butylsulfinyl)piperidine and its enantiomer is detailed. The sequence requires only two synthetic operations with one-column chromatography and is readily scaled up. The versatility of these chiral building blocks was exemplified by the total or formal synthesis of some natural and unnatural alkaloids.
