    • note
    • We also observed that the resolution of monoacetate 2 (e.e. 88%) catalysed by supported PPL and performed following conditions used in entry 3 (Table 2), is very efficient and the e.e. have been enhanced to 97.5%, after a 4.5% conversion.

    • We have already demonstrated that in monohydrolysis of a some diesters, using PLE as enzyme, the rate and the enantioselectivity are strongly influenced by the presence of an organic co-solvent (Ref. Guanti, G.; Banfi, L.; Narisano, E.; Riva, R.; Thea, S. Tetrahedron Lett. 1986, 27, 4639-4642).

    • Authors of Ref. 4d experienced the same behaviour during the hydrogenation of 1 to give the corresponding pyperidine diol; that's the reason why they prepared that diol using a completely different approach.

    • To prevent this undesired process, usually the hydrogenation is conduced in the presence of an acid (Ref. Keay, J. in Comprehensive Organic Synthesis, Trost, B. M. Ed. 1991, vol. 8, 579-602, Pergamon Press, Oxford).

    • D of this was lower than the one reported, but, due to the volatility of this compound, we did not strip away all the solvent.
