Abstract
A new chiral bicyclic tetrahydropyridine derivative was synthesized fr om L-lysine derivatives utilizing electrochemical oxidation as a key s tep. Allyl alcohols were incorporated into the tetrahydropyridine deri vative to afford N,O-acetals, and the reaction of the resulting N,O-ac etals with a carbenoid, which was generated from Et2Zn and CH2I3, yiel ded cyclopropanated products in moderate diastereoselectivities.
