    • Considering the weak solubility of (±)-3, an attempt at resolution was tried by resorting to alcoholysis of the corresponding diacetyl derivative (±)-5 obtained by conventional acetylation with pyridine/acetic anhydride of 3,3′-dihydroxymethyl-2,2′-bipyridine and successive N-oxidation by m-CPBA. Both the lipase from P. cepacia and M. miehei were able to catalyse the alcoholysis with n-butanol in t-BME, but a poor enantioselectivity was observed and consequently this approach was not considered further.

    • R (aR)-(+)-5 28.7. Due to an anomalous chromatographic behaviour, the accurate determination of the ee of monoester 4 was not possible since the more retained enantiomer was eluted as an asymmetric very broad peak.
