Recent advances in catalytic asymmetric intermolecular oxidation of alkynes

In recent years, gold-catalyzed intermolecular alkyne oxidation by an N-oxide oxidant, which presumably involves a gold carbenoid intermediate, has attracted increasing attention because it circumvents the employment of hazardous and potentially explosive diazocarbonyl compounds as starting materials for carbene generation. More importantly, the development of a catalytic enantioselective version of the reaction can help achieve an array of asymmetric synthesis processes modified from various racemic transformations of the gold carbenoid intermediate. In this review, we will present an overview of these recent advances in the asymmetric transformations by utilizing chiral ligands, chiral N,N?-dioxides and chiral substrates, aiming to facilitate progress in this fascinating field of research.

DDX3X inhibitors, an effective way to overcome HIV-1 resistance targeting host proteins

The huge resources that had gone into Human Immunodeficiency virus (HIV) research led to the development of potent antivirals able to suppress viral load in the majority of treated patients, thus dramatically increasing the life expectancy of people living with HIV. However, life-long treatments could result in the emergence of drug-resistant viruses that can progressively reduce the number of therapeutic options, facilitating the progression of the disease. In this scenario, we previously demonstrated that inhibitors of the human DDX3X helicase can represent an innovative approach for the simultaneous treatment of HIV and other viral infections such as Hepatitis c virus (HCV). We reported herein 6b, a novel DDX3X inhibitor that thanks to its distinct target of action is effective against HIV-1 strains resistant to currently approved drugs. Its improved in vitro ADME properties allowed us to perform preliminary in vivo studies in mice, which highlighted optimal biocompatibility and an improved bioavailability. These results represent a significant advancement in the development of DDX3X inhibitors as a novel class of broad spectrum and safe anti-HIV-1 drugs.

Electron interaction with deoxyribose analogue molecules in gaseous phase

We present recent results on elastic and inelastic low/medium energy electron interaction with tetrahydrofuran, C4H8O, tetrahydrofurfuryl alcohol, C5H10O2 and 3-hydroxytetrahydrofuran, C4H8O2 molecules in gaseous phase. A comparative study of both absolute differential cross sections for elastic electron scattering and electron energy loss spectra, in a wide incident electron energy range from 50 to 300 eV, has been given. The measurements of the cross sections were performed both as a function of scattering angle and incident electron energy and normalized to the absolute scale according to relative flow measurements and reliable calculations. The experimental elastic DCSs are compared with the most recent theoretical results. Both for elastic and inelastic scattering a special attention has been paid to investigate potential differences in electron scattering processes upon substitution of one of the H-atom in tetrahydrofuran by the OH group (in 3-hydroxytetrahydrofuran) or CH2OH group (in tetrahydrofurfuryl alcohol).

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.COA of Formula: C4H8O2, you can also check out more blogs about453-20-3

Aldol additions of pinacolone lithium enolate with ketones: Reactivities governed predominantly by field effects

The relative reactivities of representative alpha- and beta-heterosubstituted acyclic, cyclic (five- and six-membered), and aromatic ketones with the lithium enolate of pinacolone in diethyl ether at -78 C were determined. The order of reactivities of monosubstituted acetones (MeCOCH2X) is X = Cl > OTBDMS > OMe > SMe > NMe2 > CH2SMe > H > Me and spans a range of 104. Excellent correlation was obtained for MeCOCH2X when log (kX/kMe) was plotted against sigmaI(X) (r = 0.996, rho = 6.62), demonstrating the overwhelming importance of substituent field/inductive effects in the rate enhancement. Similar linear relationships were also observed for aromatic ketones (r = 0.993, rho = 7.61) as well as five-membered (r = 0.997, p – 6.87) and six-membered ring (r = 0.998, rho = 6.92) cyclic ketones. Thiacyclopentanone and 3- and 4-thiacyclohexanones were unique among the substrates studied in departing significantly from the correlations shown by all other types of substrates. Similarities of the reactivities for 3-oxacyclohexanone vs cyclohexanone and of 3-oxacyclopentanone vs cyclopentanone to that for methoxyacetone vs butanone established that chelation has no role in the very large rate enhancements observed. The synthetic utility of this effect for regioselective additions was demonstrated by the exclusive addition of pinacolone lithium enolate to the 2-carbonyl in MeCO(CH2)3COCH2OSiMe2t-Bu. Steric retardation by alpha-methyl and alpha-methoxy groups was nearly absent in cyclopentanones, small in acyclic ketones, and considerable in cyclohexanones.
