Controllable Intramolecular Unactivated C(sp3)-H Amination and Oxygenation of Carbamates

Dual catalyst-controlled intramolecular unactivated C(sp3)-H amination and oxygenation of carbamates merging visible-light photocatalysis and earth-abundant transition metal catalysis have been reported. Useful amino alcohol and diol derivatives could be selectively obtained from readily available tertiary alcohol derivatives. The possible mechanisms have been proposed via a 1,5-HAT process followed by Lewis acid-controlled cyclization. The nickel and zinc catalysts inhibit the formation of oxygenation and amination products, respectively. An interesting phenomenon of chirality transfer is also observed.

Synthetic Route of 2081-44-9. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 2081-44-9, Name is Tetrahydro-2H-pyran-4-ol. In a document type is Article, introducing its new discovery.

Design, synthesis, and evaluation of orally active 4-(2,4-difluoro-5- (methoxycarbamoyl)phenylamino)pyrrolo[2,1-f][1,2,4]triazines as dual vascular endothelial growth factor receptor-2 and fibroblast growth factor receptor-1 inhibitors

A series of substituted 4-(2,4-difluoro-5-(methoxycarbamoyl)phenylamino) pyrrolo[2,1-f][1,2,4]-triazines was identified as potent and selective inhibitors of the tyrosine kinase activity of the growth factor receptors VEGFR-2 (Flk-1, KDR) and FGFR-1. The enzyme kinetics associated with the VEGFR-2 inhibition of compound 50 (Ki = 52 ¡À 3 nM) confirmed that the pyrrolo-[2,1-f][1,2,4]triazine analogues are competitive with ATP. Several analogues demonstrated low-nanomolar inhibition of VEGF- and FGF-dependent human umbilical vein endothelial cell (HUVEC) proliferation. Replacement of the C6-ester substituent of the pyrrolo[2,1-f][1,2,4]-triazine core with heterocyclic bioisosteres, such as substituted 1,3,5-oxadiazoles, afforded compounds with excellent oral bioavailability in mice (i.e., 50 Fpo = 79%). Significant antitumor efficacy was observed with compounds 44, 49, and 50 against established L2987 human lung carcinoma xenografts implanted in athymic mice. A full account of the synthesis, structure-activity relationships, pharmacology, and pharmacokinetic properties of analogues within the series is presented.

Beta-N-Acetylhexosaminidase: What’s in a name…?

Beta-N-Acetylhexosaminidases (EC 3.2.1.52, belonging to CAZy GH families 3, 20 and 84) have recently gained a lot of attention, not only due to their implication in human physiology and disease, but also due to their great potential in the enzymatic synthesis of carbohydrates and glycomimetics. GH family 20 Beta-N-acetylhexosaminidases, and GH family 3 and 84 beta-N-acetylglucosaminidases from all kinds of organisms have been intensively studied from the point of view of their physiological roles, reaction mechanisms, structure and inhibition. Thanks to their outstanding substrate promiscuity, extracellular Beta-N-acetylhexosaminidases from filamentous fungi are able to cleave and transfer substrates bearing various functionalities, ranging from carboxylates, sulfates, acylations to azides, and even 4-deoxy glycosides. Thus, they have proved to be versatile biosynthetic tools for the preparation of both natural and modified hexosaminides under mild conditions with good yields.

Practical de-O-acylation reactions promoted by molecular sieves

Methanol dried extensively over molecular sieves, or methanol in combination with powdered molecular sieves, serves as a good acceptor for acyl transfer reactions. Several O-acetylated and O-benzoylated sugar derivatives were efficiently de-O-acylated using this approach. In the case of per-O-acetylated N-acetylglucosamine, selective anomeric deprotection could be effected in high yield.

Fluxional chromophores of bis(di-2-pyridylamine)nitritocopper(II) cations: Crystal structures and electronic properties of the complexes bis(di-2-pyridylamine)nitritocopper(II) nitrate and bis(di-2-pyridylamine)nitritocopper(II) perchlorate

The X-ray crystal structures of two cation-distortion isomers of [Cu(dpyam)2(ONO)](NO3) (1) and [Cu(dpyam)2(ONO)](ClO4) (2) complexes are reported and shown to contain an asymmetric cis-distorted CuN4O2 chromophore. In 1 the copper atom and the asymmetrically bonded nitrito group lie on a crystallographic C2 axis. The nitrito group is clearly disordered about the C2 axis giving a square pyramidal cis-distorted octahedral (4+1+1*) chromophore rather than a pseudo regular cis-distorted octahedral chromphore. In 2 a distortion of the CuN4O2 chromophore towards a square pyramidal (4+1+1*) geometry is also present, but with well-ordered and less asymmetric nitrito group. The polycrystalline ESR spectra of 1 and 2 are temperature independent suggesting that both complexes appear to be near the static distortion limit of the fluxional CuN4O2 chromophore geometry. The electronic reflectance spectra of 1 and 2 involve two bands at approximately 14 700 and 9800 cm-1 for 1, and approximately 14 970 and 10 000 cm-1 for 2 and relate to the underlying static CuN4O2 (4+1+1*) chromophore geometry.
