Correction: de Gonzalo, G. Lipase Catalysed Kinetic Resolution of Racemic 1,2-Diols Containing a Chiral Quaternary Center. Molecules 2018, 23, 1585

The authors wish to make the following corrections to their paper. [...]

The authors wish to make the following corrections to their paper [1]. The authors are sorry to report that the absolute configurations of the 1,2-diols (1-5d) as well as the acetates (1-5e) obtained in this paper are inverted. In order to establish the absolute configuration of these compounds, specific rotation values should be compared with those described in [2] for (R)-1d, (R)-4d and (R)-5d, instead of the value provided in [3] for (R)-ethyl 2-benzyl-2,3-dihydroxypropanoate. This compound is the benzylic analogue of 1,2-diols 1-5d. Compound 6d (ethyl 2-hydroxy-2-hydroxymethyl-4-phenylbutanoate) presents the chiral quaternary center bound to an aliphatic carbon instead of an aromatic one. Thus, specific rotation values cannot be compared with the ones given in [2], and only the relative configurations of 6d and 6e are indicated. Consequently, the authors wish to make the following corrections to the paper: In the enzymatic kinetic resolutions of 1,2-diols containing the chiral center bound to an aromatic carbon atom, (S)-1,2-diols (S)-1-5d and (R)-acetates (R)-1-5e are obtained. With regard to substrate 6d, the 1,2-diol achieved was (−)-6d, whereas the acetate obtained was (+)-6e.
