Preparation of Chitosan-supported Urea Materials and their Application in Some Organocatalytic Procedures
(Elsevier, 2018)
An efficient and mild procedure was developed for the preparation of three chitosan-supported ureas containing electron-withdrawing groups. These catalysts were characterized and employed as organocatalysts in different ...

Stereoselective enzymatic reduction of 1,4-diaryl-1,4-diones to the corresponding diols employing alcohol dehydrogenases
(MDPI, 2018)
Due to the steric hindrance of the starting prochiral ketones, the preparation of chiral 1,4-diaryl-1,4-diols through the asymmetric hydrogen transfer reaction has been mainly restricted to the use of metal-based catalysts, ...

Lipase catalysed kinetic resolution of racemic 1,2-diols containing a chiral quaternary center
(MDPI, 2018)
Optically active 1,2-diols are valuable buildings blocks in organic synthesis. In the present paper, a set of racemic 1,2-diols with an ester functional group are prepared, starting from -ketoesters in a three-step ...
