Microbial Stereoselective One-Step Conversion of Diols to Chiral Lactones in Yeast Cultures
It has been shown that whole cells of different strains of yeast catalyze stereoselective oxidation of meso diols to the corresponding chiral lactones. Among screening-scale experiments, Candida pelliculosa ZP22 was selected as the most effective biocatalyst for the oxidation of monocyclic diols 3a–b with respect to the ratio of high conversion to stereoselectivity. This strain was used in the ...
متن کاملCrystal structure and absolute configuration of (3aR,3′aR,7aS,7′aS)-2,2,2′,2′-tetramethyl-3a,6,7,7a,3′a,6′,7′,7′a-octahydro-4,4′-bi[1,3-benzodioxolyl], obtained from a Pd-catalyzed homocoupling reaction
The absolute configuration, i.e. (3aR,3'aR,7aS,7'aS), of the title compound, C18H26O4, synthesized via a palladium-catalyzed homocoupling reaction, was determined on the basis of the synthetic pathway and was confirmed by X-ray diffraction. The homocoupled mol-ecule is formed by two chemically identical moieties built up from two five- and six-membered fused rings. The supra-molecular assembly ...

In the title compound, C(25)H(32)Cl(2)N(2)O(2), there are two intra-molecular O-H⋯ N hydrogen-bonding inter-actions between the hy-droxy groups on the aromatic rings and the two N atoms of the heterocyclic group. The cyclo-hexane ring adopts a chair conformation and the imidazolidine unit to which it is fused has a twisted envelope conformation. The asymmetric unit comprises one half-mol-ecule ...

In the tetra-hydro-isoindole moiety of the title compound, C(17)H(17)NO(3)S, the six-membered ring assumes a boat configuration and the -S=O group bridges the prow and stern of the boat. The phenyl ring is oriented at a dihedral angle of 83.2 (1)° with respect to the pyrrole ring. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. A weak C...
