    • In ref. 11, the experimental details were not described and the obtained alkylated piperidine β-amino esters were only partially characterized. Moreover, the optical rotation values have been mistakenly reported as positive, and must be read as negative.

    • The procedure was improved by the successful purification of 1 by a very short column filtration on silica gel (AcOEt) with a similar yield (87%).

    • 2/C catalyzed hydrogenation (0.15 equiv in weight) of 1 was also carried out with a similar diastereoselectivity, provided that two additions of the catalyst were performed successively (0.05 equiv for 12h and 0.10 equiv for 3h).
