Boron-mediated directed aromatic C?H hydroxylation

Transition metal-catalysed C?H hydroxylation is one of the most notable advances in synthetic chemistry during the past few decades and it has been widely employed in the preparation of alcohols and phenols. The site-selective hydroxylation of aromatic C?H bonds under mild conditions, especially in the context of substituted (hetero)arenes with diverse functional groups, remains a challenge. Here, we report a general and mild chelation-assisted C?H hydroxylation of (hetero)arenes mediated by boron species without the use of any transition metals. Diverse (hetero)arenes bearing amide directing groups can be utilized for ortho C?H hydroxylation under mild reaction conditions and with broad functional group compatibility. Additionally, this transition metal-free strategy can be extended to synthesize C7 and C4-hydroxylated indoles. By utilizing the present method, the formal synthesis of several phenol intermediates to bioactive molecules is demonstrated.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 497-25-6, help many people in the next few years.Safety of Oxazolidin-2-one

Synthesis of anisolylated aspartyl and glutamyl tripeptides

A process has been developed for transforming the beta-carboxyl of aspartate and the gamma-carboxyl of glutamate into anisolyl ketones. These ketones are occasional byproducts in peptide synthesis, resulting from deprotection or resin-removal processes in the presence of anisole as a scavenger. The ketone amino acids have been incorporated in a tripeptide by coupling with CBMIT. During peptide bond formation the keto group of the glutamyl residue required protection, which was provided as the ethylene dithioketal.

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.Recommanded Product: Isoxazolidine hydrochloride, you can also check out more blogs about39657-45-9

Enantioselective Total Synthesis of Antibiotic CJ-16,264, Synthesis and Biological Evaluation of Designed Analogues, and Discovery of Highly Potent and Simpler Antibacterial Agents

An improved and enantioselective total synthesis of antibiotic CJ-16,264 through a practical kinetic resolution and an iodolactonization reaction to form the iodo pyrrolizidinone fragment of the molecule is described. A series of racemic and enantiopure analogues of CJ-16,264 was designed and synthesized through the developed synthetic technologies and tested against drug-resistant bacterial strains. These studies led to interesting structure-activity relationships and the identification of a number of simpler, and yet equipotent, or even more potent, antibacterial agents than the natural product, thereby setting the foundation for further investigations in the quest for new anti-infective drugs.

The degradation of DGEBA/DICY under 100 keV proton irradiation

The degradation process of diglycidyl ether of bisphenol A (DGEBA)/ dicyandimide (DICY) solidified system under 100 keV proton irradiation was investigated. It was found that the proton irradiation results in mass loss, which the maximum is approximately 15.5 mug/cm2, and change in surface morphology of DGEBA/DICY. The analyses of FT-IR and XPS showed that, the proton irradiation induces the debonding of the weak groups such as -CH 3, C-O, leading to formation of stable carbon-rich structure by recombination of the occurred free radicals, and chemical reaction between the free radicals with participation of proton. The degradation of DGEBA/DICY exhibits exponential variation with the proton fluence, which the degradation rate is high at the initial stage of irradiation, and becomes slow trending to constant after the proton fluence reaches 6 ¡Á 1015 /cm 2.
