Phenylglycine methyl ester, a useful tool for absolute configuration determination of various chiral carboxylic acids

A new chiral anisotropic reagent, phenylglycine methyl ester (PGME), developed for the elucidation of the absolute configuration of chiral alpha,alpha- disubstituted acetic acids, has turned out to be applicable to other substituted carboxylic acids, such as chiral alpha-hydroxy-, alpha-alkoxy-, and alpha- acyloxy-alpha,alpha-disubstituted acetic acids, as well as to chiral beta,beta- disubstituted propionic acids. Because a carboxylic moiety is convertible from other functional groups, e.g., ozonolysis of an olefin and oxidative cleavage of a glycol, the present findings can expand the utility of the PGME method to the absolute configuration determination of various types of organic compounds, even those which initially lack oxygen functions. Several examples of the combination of chemical reactions and the PGME method are described.

Continuous-Flow Production of Succinic Anhydrides via Catalytic beta-Lactone Carbonylation by Co(CO)4?Cr-MIL-101

Industrial synthesis of succinic acid relies on hydrocarbon oxidation or biomass fermentation routes that suffer from energy-costly separation processes. Here we demonstrate an alternate route to succinic anhydrides via beta-lactone carbonylation by heterogeneous bimetallic ion-pair catalysis in Co(CO)4–incorporated Cr-MIL-101 (Co(CO)4Cr-MIL-101, Cr-MIL-101 = Cr3O(BDC)3F, H2BDC = 1,4-benzenedicarboxylic acid). Postsynthetically introduced Co(CO)4- facilitates CO insertion to beta-lactone substrates activated by the Lewis acidic Cr(III) centers of the metal-organic framework (MOF), leading to catalytic carbonylation with activity and selectivity profiles that compare favorably to those reported for homogeneous ion-pair catalysts. Moreover, the heterogeneous nature of the MOF catalyst enables continuous production of succinic anhydride through a packed bed reactor, with room temperature beta-propiolactone carbonylation activity of 1300 molAnhydride¡¤molCo-1 over 6 h on stream. Simple evaporation of the fully converted product stream yields the desired anhydride as isolated solids, highlighting the unique processing advantages conferred by this first example of heterogeneous beta-lactone carbonylation pathway.

Asymmetric one-pot reactions using heterogeneous chemical catalysis: Recent steps towards sustainable processes

The preparation of optically pure fine chemicals is among the most important and challenging tasks met by organic chemists. Recently, significant efforts have been focused on the development of green and sustainable procedures for the synthesis of these high value-added compounds. Asymmetric heterogeneous catalysis has provided efficient solutions to these challenges. The application of heterogeneous chiral catalysts in one-pot processes combines the advantages of use of these materials with time, material, and energy savings associated with cascade or sequential procedures. This review surveys these asymmetric one-pot reactions reported until July 2017, in which a heterogeneous chemical catalyst has been applied either as a single multifunctional catalyst or in combination with a second catalytically active material. These processes include one-pot procedures catalysed by carefully designed solids obtained by the immobilization of chiral metal complexes, by anchoring chiral organocatalysts, or by modifying catalytic surfaces with optically pure compounds, which may also incorporate uncatalyzed and homogeneously catalysed steps. Methods applying achiral heterogeneous catalysts in combination with soluble chiral chemical catalysts or biocatalysts are also presented. Sophisticated, finely tuned materials have been applied in most of these reactions, which have been discussed along with the main requirements necessary to perform these transformations in a one-pot manner.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 53558-93-3, you can also check out more blogs about53558-93-3

Recent advances in the development of ubiquitin-specific-processing protease 7 (USP7) inhibitors

Ubiquitin-specific-processing protease 7 (USP7) is one among the several deubiquitinating enzymes gaining central attention in the current cancer research. Most recent studies have focused on illustrating how USP7 is involved in the cancer process, while few articles reported the development of small molecule USP7 inhibitors. Although some review articles dealt with USP7, they mainly focused on its physiological role and not on the development of USP7 inhibitors. In this review, we systematically summarise the structures, activities and structure-activity relationship (SAR) of small molecule USP7 inhibitors, recently disclosed in scientific articles and patents from 2000 to 2019. The binding modes of typical compounds and their interactions with USP7 are also presented, while other deubiquitinase inhibitors are described in detail. Meanwhile, we briefly introduce the biochemical and physiological functions of USP7. Finally, challenges and potential strategies in developing small molecule USP7 inhibitors are also discussed.

Periodic pattern of iron oxide using 2D microgel colloidal crystal as template

High-throughput and low-cost methods for the fabrication of 2D patterned structures are highly desirable. Herein we proposed a new colloidal lithography method using 2D microgel colloidal crystal (CC) as template. Unlike the previously developed methods in which the microgel spheres act as lithography mask, herein they act as nanoreactors to convert a precursor into the target product. As an example, highly ordered 2D CC of poly(N-isopropylacrylamide-co-acrylic acid) (P(NIPAM-AA)) microgel was prepared on charge-reversible silicon wafer. The template was first treated with trimethylchlorosilane (TMCS) and then loaded with Fe(NO3)3. Finally the polymer was removed and Fe(NO3)3 was converted in situ to Fe2O3 by calcination, and an ordered Fe2O3 array was obtained. The composition left after calcination was confirmed to be Fe2O3 by XPS. TMCS treatment was demonstrated to be necessary to obtain arrays of discrete patches, instead of continuous film. 0.2 mM Fe(NO3)3 solution was found to be optimal for Fe(NO3)3 loading. A calcination temperature of 600 C was high enough to remove the polymeric materials and convert Fe(NO3)3 to Fe2O3. The method not only allows constructing ordered structures in a simple and cost-efficient way, but also adjusting the parameters of the pattern by adjusting the parameters of the template.

Design and synthesis of an orally bioavailable and selective peptide epoxyketone proteasome inhibitor (PR-047)

Proteasome inhibition has been validated as a therapeutic modality in the treatment of multiple myeloma and Non-Hodgkin’s lymphoma. Carfilzomib, an epoxyketone currently undergoing clinical trials in malignant diseases, is a highly selective inhibitor of the chymotrypsin-like (CT-L) activity of the proteasome. A chemistry effort was initiated to discover orally bioavailable analogues of carfilzomib, which would have potential for improved dosing flexibility and patient convenience over intravenously administered agents. The lead compound, 2-Me-5-thiazole-Ser(OMe)-Ser(OMe)-Phe-ketoepoxide (58) (PR-047), selectively inhibited CT-L activity of both the constitutive proteasome (beta5) and immunoproteasome (LMP7) and demonstrated an absolute bioavailability of up to 39% in rodents and dogs. It was well tolerated with repeated oral administration at doses resulting in >proteasome inhibition in most tissues and elicited an antitumor response equivalent to intravenously administered carfilzomib in multiple human tumor xenograft and mouse syngeneic models. The favorable pharmacologic profile supports its further development for the treatment of malignant diseases.
