oxypiperidine (4), prepared from l-lysine by using electrochemical oxidation, was cyclopropanated with high diastereoselectivity (96.6% de), and the cyclopropanated product was transformed to opticallyactive 2,3-methanopipecolic acid (1). In this transformation, the 6-methoxy group of 4 was found to be an effective chiral auxiliary.
