Process for the preparation of 3,4-dihydroxybutanoic acid and derivatives thereof from substituted pentose sugars

A process for the preparation of 3,4-dihydroxybutanoic acid (I) and 3-hydroxy-gamma-butyrolactone (V) thereof from a 3-leaving group substituted pentose source is described. In particular, the process relates to the synthesis of (R)-3,4-dihydroxybutanoic acid and (R)-3-hydroxy-gamma-butyrolactone from a 3-leaving group substituted L-pentose sugars. The process uses a base and a peroxide to convert the pentose source to the chiral 3,4-dihydroxybutanoic acid compound. The chiral 3,4-dihydroxybutanoic acid can be further converted to 3-hydroxy-gamma-butyrolactone by acidification. The chiral compound is useful as a chemical intermediate to the synthesis of various drugs and other products.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 7331-52-4 is helpful to your research. Application of 7331-52-4

Dose-dependent antithrombotic activity of an orally active tissue factor/factor VIIa inhibitor without concomitant enhancement of bleeding propensity

The discovery of a highly potent and selective tissue factor/factor VIIa inhibitor is described. Upon oral administration of its double prodrug in the guinea pig, a dose-dependent antithrombotic effect is observed in an established model of arterial thrombosis without prolonging bleeding time. The pharmacodynamic properties of this selective inhibitor are compared to the behaviour of a mixed factor VIIa/factor Xa inhibitor.

A newly isolated strain capable of effectively degrading tetrahydrofuran and its performance in a continuous flow system

A Gram-negative strain DT4, capable of growing aerobically on tetrahydrofuran (THF) as the sole carbon and energy source was isolated from a pharmaceutical wastewater treatment plant. It was identified as Pseudomonas oleovorans by morphological and physiological characteristics as well as Biolog profiling and 16S rDNA sequence. Cells of P. oleovorans DT4 pre-cultured in THF could degrade 5 mM THF completely without lag phase. The generation time of 2.7 h and the maximum degradation rate of 203.9 mg THF/(h g dry weight) were observed, demonstrating that DT4 bears the highest THF-degrading activity in ever described strains. Furthermore, THF concentration as high as 100 mM was tolerated by the culture. Several important compounds including gamma-butyrrolactone and benzene could be directly metabolized, whereas other pollutants (e.g., tetrahydropyrane) could be cometabolized by DT4. THF removal was achieved in a continuous flow system with the maximum specific growth rate 0.113 h-1 and half-saturation constant 1.224 mg/L, indicating the great potential of THF bioremediation in future full-scale application.

The cycloaddition way to novel deoxy disaccharide analogs

A novel heterocycloaddition merges 2-thiono-3-ketolactones with carbohydrate glycals to afford materials which resemble disaccharides with an O-glycosidic linkage at the anomeric center and a thioether linking both C-2 and C-2?, thus creating a third heterocyclic ring. Upon desulfurization, these novel cycloadducts afford materials which are models for 2-deoxydisaccharides. Studies with two keto lactones and seven glycals are described.

Treasures old and new: What we can learn regarding the macrocyclic problem from past and present efforts in natural product total synthesis

In this review the strategies leading to successful macrocyclization, in the context of total synthesis are discussed. These synthetic endeavors will be discussed paying particular attention to the methods employed, and including the type of reactive intermediates that could play a key role in key cyclization steps. In many cases “simple” macrocyclization methods were found to be inadequate, and alternative creative approaches were required. For example, we describe Boger’s imaginative development of the intramolecular version of the Larock annulation which yielded the chloropeptin 1 DEF macrocycle. Peptide coupling approaches were unsuccessful. In another example, a key macrocyclic domain within diazonamide was beautifully installed (Nicolaou, et al.) by single electron oxidation/reduction (Witkop reaction), thereby establishing a crucial biaryl functionality. In contrast, oxidative methodologies failed to deliver the distorted biaryl found in haouamine, and Baran, et al. subsequently exploited a spectacular pyrone N-butyne intramolecular Diels-Alder reaction to install this biaryl moiety. Other unexpected and mechanistically intriguing observations will be described throughout the review.
