Efficient general synthesis of 1,2- and 1,3-Diols in high enantiomeric excess via the intramolecular asymmetric reduction of the corresponding ketoalkyl diisopinocampheylborinate intermediates

The first successful asymmetric reduction of unhindered aliphatic ketones with B-chlorodiisopinocampheylborane is reported. In contrast to the reduction in high ee of aralkyl ketones, such as acetophenone, with the reagent, the reduction of unhindered dialkyl ketones, such as 3-methyl-2-butanone, provides only poor ee. However, treatment of alpha- and beta-hydroxyketones with one equiv of diisopnocampheylborane or B-chlorodiisopinocampheylborane rapidly produces the corresponding ketoalkyl diisopinocampheylborinate intermediates, which then undergo facile intramolecular reduction. This reaction sequence, followed by oxidative workup, provides a general synthesis of 1,2- and 1,3-diols in 84?99% enantiomeric excess.

Chirality driven metallic versus semiconducting behavior in a complete series of radical cation salts based on dimethyl-ethylenedithio- tetrathiafulvalene (DM-EDT-TTF)

Enantiopure (S,S) and (R,R) dimethyl-ethylenedithio-tetrathiafulvalene (DM-EDT-TTF) 1 donors are synthesized by cross coupling followed by decarboxylation reactions. In the solid state the methyl groups are arranged in axial positions within sofa-type conformation for the six-membered rings. Crystalline radical cation salts formulated as [(S,S)-1]2PF 6, [(R,R)-1]2PF6, and [(rac)-1] 2PF6 are obtained by electrocrystallization. When the experiment is conducted with enantioenriched mixtures both enantiopure and racemic phases are obtained. The monoclinic enantiopure salts, containing four independent donors in the unit cell, show semiconducting behavior supported by band structure calculations of extended Hueckel type. The racemic salt contains only one independent donor in the mixed valence oxidation state +0.5. Under ambient pressure the racemic material is metallic down to 120 K, while an applied pressure of 11.5 kbar completely suppresses the metal-insulator transition. Band structure calculations yield an open Fermi surface, typical for a pseudo-one-dimensional metal, with unperfected nesting, thus ruling out the possibility of charge or spin density modulations to be at the origin of the transition. Raman spectroscopy measurements, in agreement with structural analysis at 100 K, show no indication of low-temperature charge ordering in the racemic material at ambient pressure, thus suggesting Mott-type charge localization for the observed metal-insulator transition.

On the origin of changes in topicity observed in Diels-Alder reactions catalyzed by Ti-TADDOLates

New C2 symmetric TADDOLs containing different groups at the 2-position of the dioxolane ring have been prepared. The Ti catalysts derived from these have been studied in the Diels-Alder reaction of cyclopentadiene and (E)-2-butenoyl-1,3-oxazolidin-2-one. Substituents at the C-2 position of the dioxolane ring can play an important role in determining the selectivity as well as the nature of the major isomer. This effect is more important for TADDOLs containing bulky aromatic groups such as 3,5-dimethylphenyl- or 1-naphthyl at the alpha-positions. Experimental evidence supports the hypothesis that pi-pi interactions between aromatic groups at the C-2 and the ones at the alpha-positions are critical in this respect.

The discovery of tertiary-amine LXR agonists with potent cholesterol efflux activity in macrophages

The liver X receptors (LXR) play a key role in cholesterol homeostasis and lipid metabolism. SAR studies around tertiary-amine lead molecule 2, an LXR full agonist, revealed that steric and conformational changes to the acetic acid and propanolamine groups produce dramatic effects on agonist efficacy and potency. The new analogs possess good functional activity, demonstrating the ability to upregulate LXR target genes, as well as promote cholesterol efflux in macrophages.

Metabolites recovery from fermentation broths via pressure-driven membrane processes

The production of specific metabolites using microorganism has been promoted and enhanced by two different approaches, such as modification of the metabolic pathways of microorganism and optimization of culture medium conditions to synthesize specific compounds. However, research community is today focused on the development of processes and techniques for a suitable recovery of metabolites from different stages of fermentation. For this purpose, the use of organic solvents has been the most common approach for the recovery of specific target compounds according to the solvent affinity. Additionally, these techniques also require the implementation of unit processes to obtain better recovery rates; it means that solvent extraction methods need the implementation of additional steps to recover the solvents used, which may involve the increase of final costs in the production process. For this reason, researchers have started to consider membrane-based technologies (e.g. microfiltration [MF], ultrafiltration [UF], and nanofiltration [NF]), as an alternative for the recovery of metabolites from fermentation broths. Therefore, the objective of this paper is to provide an overview of the current findings of the recovery of metabolites from fermentation broths by means of pressure-driven membrane processes. Particular attention will be paid to relevant data, analyzing and discussing according to the membrane features, metabolite properties, and some other phenomena that influence in the separation. Moreover, a framework of the application of the MF, UF, and NF processes in solutes recovery is addressed. Finally, some fundamentals of these processes are also given.

Preparation of Optically Active 1,2-Diols and alpha-Hydroxy Ketones Using Glycerol Dehydrogenase as Catalyst: Limits to Enzyme-Catalyzed Synthesis due to Noncompetitive and Mixed Inhibition by Product

Glycerol dehydrogenase (GDH, EC 1.1.1.6, from Enterobacter aerogenes or Cellulomonas sp.) catalyzes the interconversion of analogues of glycerol and dihydroxyacetone.Its substrate specificity is quite different from than of horse liver alcohol dehydrogenase (HLADH), yeast alcohol dehydrogenase, and other alcohol dehydrogenases used in enzyme-catalyzed organic synthesis and is thus a useful new enzymic catalyst for the synthesis of enantiomerically enriched and isotopically labeled organic molecules.This paper illustrates synthetic applications of GDH as a reduction catalyst by the enantioselective reduction of 1-hydroxy-2-propanone and 1-hydroxy-2-butanone to the corresponding R 1,2-diols (ee = 95-98percent). (R)-1,2-Butanediol-2-d1 was prepared by using formate-d1 as the ultimate reducing agent.Comparison of (R)-1,2-butanediol prepared by reduction of 1-hydroxy-2-butanone enzymatically and with actively fermenting bakers’ yeast indicated than yield and enantiomeric purity were similar by the two procedures.Reactions proceeding in the direction of substrate oxidation usually suffer from slow rates and incomplete conversions due to product inhibition.The kinetic consequences of product inhibition (competitive, noncompetitive, and mixed) for practical synthetic applications of GDH, HLADH, and other oxidoreductases are analyzed.In general, product inhibition seems the most serious limitation to the use of these enzymes as oxidation catalysts in organic synthesis.
