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.

PPL catalysed acetylation of 4 was already reported (Cesti, P.; Zaks, A.; Klibanov, A. M. Appl. Biochem. Biotechnol. 1985, 11, 401-407). However the e.e. was not determined.

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).

note

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.
