All enantiomeric excesses were determined by HPLC with a chiral column (Chiracel OD-H 0.46×15 cm). For (E)-2 separation conditions: elution with a mixture of hexane/i-PrOH 99:1 v/v; flow rate: 0.5 ml/min; retention time 14.1 min for minor enantiomer and 15.1 min for major.

Other allylic organometallic reagents (Zn, Cu, Ce) were also tried, but no reaction (with Cu and Zn) or lower yield with similar diastereoselectivity (with Ce) were noted.

note

The trans configuration assignment for compound 8a is consistent with the conversion of this intermediate into known deprotected trans-2,6-dialkyl-tetrahydropyridine derivative and comparison of the NMR data reported in the literature, see: Pernerstorfer, J.; Schuster, M.; Blechert, S. Synthesis 1999, 138-144. The trans configuration of 8c was attributed by conversion of the minor cis isomer 8c into known deprotected cis-2,6-dialkyl-piperidine, see: Åhman, J.; Somfai, P. Tetrahedron 1995, 51, 9747-9756.
