Synthesis of optically active beta-benzyl-gamma-butyrolactone through lipase-catalyzed kinetic resolution

The lipase-catalyzed kinetic resolution of the racemic gamma-hydroxy ester 2, coupled with subsequent acid-mediated cyclization, is an effective method for the synthesis of both enantiomers of beta-benzyl-gamma-butyrolactone 1. This enzymatic process affords the product with high enantiomeric excess under mild reaction conditions and does not require optically active starting materials.

Application of Tsunoda reagent to the convenient synthesis of drug-like pyrazoles

The versatility of the under-utilised (cyanomethylene)tributylphosphorane (CMBP, Tsunoda reagent) was demonstrated on two occasions in a drug discovery context. Firstly, the high reactivity of the phosphorane allowed the alkylation of a weakly acidic pyrazole when standard Mitsunobu conditions were unsuccessful. Secondly, the clean reaction profile generally obtained using CMBP allowed the direct use of the crude mixture in a subsequent Suzuki cross coupling. This reagent has utility when isolation of the Mitsunobu reaction product (e.g. containing a boronate) is not desirable.

Process for preparing optically active tetrahydro-2-furoic acid

A process for preparing an optically active tetrahydro-2-furoic acid is disclosed. The process comprises (i) reacting (¡À)-tetrahydro-2-furoic acid with an optically active amine resolver of the following formula (I): STR1 wherein R1 is a lower alkyl group and R2 represents an alkyl group or ar aryl group, provided that R1 and R2 are different from each other, thus producing an optically active diastereomer salt, and (ii) decomposing the diastereomer salt. According to the process, a high purity, optically active tetrahydro-2-furoic acid can be prepared at a high yield using an amine resolver. The amine resolver can be recovered at a high yield and high purity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C5H8O3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 87392-05-0, in my other articles.

Recently, we disclosed a new class of HCV polymerase inhibitors discovered through high-throughput screening (HTS) of the GlaxoSmithKline proprietary compound collection. This interesting class of 3-(1,1-dioxo-2H-1,2,4- benzothiadiazin-3-yl)-4-hydroxy-2(1H)-quinolinones potently inhibits HCV polymerase enzymatic activity and inhibits the ability of the subgenomic HCV replicon to replicate in Huh-7 cells. This report will focus on the structure-activity relationships (SAR) of substituents on the quinolinone ring, culminating in the discovery of 1-(2-cyclopropylethyl)-3-(1,1-dioxo-2H-1,2,4- benzothiadiazin-3-yl)-6-fluoro-4-hydroxy-2(1H)-quinolinone (130), an inhibitor with excellent potency in biochemical and cellular assays possessing attractive molecular properties for advancement as a clinical candidate.

Bioactive marine sesterterpenoids

Terpenoids are by far the largest class of natural products. Within this class of compounds, the sesterterpenes form a rare group of isoprenoids, which occur in widely differing source. Marine organisms have provided a large number of sesterterpenoids, possessing novel carbon skeleton and a wide variety of biological activities. The more significant sesterterpenoids from marine organisms, which show biological activities, are reported and they are grouped in a biogenetic sequence. Natural products that do not contain 25 carbon atoms but are obviously sesterterpene derivatives are also included. The anti-inflammatory activity is the most relevant among the biological activities observed for marine sesterterpenoids. The high potential for some of these products suggested that they could be developed as drugs for the treatment of inflammation. The different directions that can be taken to obtain quantities of secondary metabolites are reported.

Quantitative Measurements of Polymer Hydrophobicity Based on Functional Group Identity and Oligomer Length

A combined experimental and computational investigation revealed a hydrophobicity trend for oxygen-containing functional groups commonly encountered in monomers and polymers. Based on solvatochromatic dye experiments, HPLC retention times, and theoretical LogP values, the arrangement of the three oxygen atoms in carbonates results in more hydrophobicity than other permutations like anhydrides. Another trend emerged for functional groups with two oxygen atoms (acetals > esters). Overall, when comparing aliphatic polymers with similarly sized monomers, hydrophobicity decreased as follows: carbonates > acetals > esters > anhydrides. These trends have important implications for degradation, conductivity, and many other applications.
