The CAS is 150-19-6. Through research, I have a further understanding and discovery of m-Methoxyphenol

The first palladium-catalyzed cross-coupling reaction of aryl/heteroaryl and alkenyl mesylates and tosylates with aryl titanium as the multi-functional reagent is reported. Using the catalyst system of Pd(OAc)(2) associated with the new NMe2-CM-Phos (L14), a broad range of electron-rich, electron-neutral, electron-deficient, and sterically hindered aryl/heteroaryl and alkenyl mesylates and tosylates are well coupled with aryl titanium reagents to give the corresponding products in good to excellent yields. The catalyst loading down to 0.2 mol% Pd and the reaction time shortening to 10 min can be achieved. The reaction can be easily scaled up to the gram scale without diminishing the product yield.

A new method for the fast synthesis of diverse 4-aryl-6-cycloamino-1,3,5-triazin-2-amines was developed. The synthesis is performed under microwave irradiation in a one-pot manner from cyanoguanidine, aromatic aldehydes, and cyclic amines. Their three-component reaction in the presence of hydrochloric acid produced dihydrotriazines, which were then converted (without isolation) into the targeted compounds via aromatic dehydrogenation in the presence of alkali. The reaction tolerated various aromatic aldehydes (including heterocyclic) and cyclic amities. Crystal structures of two representative 4-aryl-6-morpholino-1,3,5-triazin-2-amines were established by X-ray crystallography. The results of preliminary biological screening identified potent antileukemic activity for 6-[3,4-dihydroisoquinolin-2(1H)-yl]-4- phenyl-1,3,5-triazin-2-amine.

We report a new method for constructing propionate-derived trisubstituted alkene motifs in a stereoselective manner. 1-Substituted 1,1-di(pinacolatoboryl)-(E)-alk-2-enes are generated in situ from 1-substituted 1,1-di(pinacolatoboryl)alk-3-enes through ruthenium(II)-catalyzed double-bond transposition. These species undergo a chiral phosphoric acid catalyzed allylation reaction of aldehydes to produce the E isomers of anti-homoallylic alcohols. On the other hand, the corresponding Z isomers of anti-homoallylic alcohols are obtained when a dimeric palladium(I) complex is employed as the catalyst for this double-bond transposition. Thus, both E and Z isomers can be synthesized from the same starting materials. A B-C(sp(2)) bond remaining with the allylation product undergoes the Suzuki-Miyaura cross-coupling reaction to furnish a propionate-derived trisubstituted alkene motif in a stereo-defined form. The present method to construct the motifs with (E)- and (Z)-alkenes are successfully applied to the syntheses of (+)-isotrichostatic acid, (-)-isotrichostatin RK, and (+)-trichostatic acid, respectively.

Lipid removal of Asian sea bass skin pretreated with pulsed electric field (PEF) at 24 kV/cm for 72 ms, followed by hydrolysis with porcine pancreas lipase (PPL) at 42.36 U/g skin dry matter with the aid of vacuum impregnation (VI) at various vacuum times (10, 15, 20 and 30 min) was investigated. The highest lipid reduction in PEF-treated skin was found at vacuum time of 20 min (p < 0.05). The efficacy of defatting was increased with increasing VI cycles (p < 0.05), in which lipids were eliminated by 97% when VI cycles of 4 were used. Also, the lipid content was lower than that found in sample treated with 30% isopropanol under the same VI condition (p < 0.05). Moreover, lipids extracted from PEF-VI-PPL treated skin had lower monounsaturated and polyunsaturated fatty acid contents as compared to other samples. Lower lipid distribution was noticeable in PEF-VIPPL treated skin. When PEF-VI-PPL-treated skin was hydrolyzed using papain at 0.3 U/g dry skin matter, weak fishy odor/flavor of the resulting hydrolyzed collagen was observed, compared with other samples (p < 0.05). Additionally, there was the reduced abundance of volatile compounds. Thus, the use of PPL in conjunction with VI could remove lipid in PEF-treated skin effectively.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

Enantioselective alpha-aminomethylation of carbonyl compounds constitutes a powerful protocol for introducing aminomethyl groups to simple organic molecules. However, current strategies rely on nucleophile-based enantioselective activation with inherently activated substrates only, and enantioselective protocol based on the activation of in situ-generated unstable formaldimines remains elusive, probably owing to their unstable nature and the lack of steric environment for efficient stereocontrols. Here, based on a rhodium/chiral phosphoric acid cooperative catalysis, we achieved an enantioselective three-component reaction of alpha-diazo ketones with alcohols and 1,3,5-triazines. A dual hydrogen bonding between the chiral phosphoric acid catalyst and two distinct active intermediates was proposed to be crucial for the efficient electrophile-based enantiocontrol. A series of chiral beta-amino-alpha-hydroxy ketones including those derived from simple aliphatic alcohols, allylic alcohol, propargyl alcohol, complicated natural alcohols and water could all be prepared in high efficiency and enantioselectivity.

Background Bisphenol A is an important organic chemical as an intermediate, final and inert ingredient in manufacturing of many important products like polycarbonate plastics, epoxy resins, flame retardants, food-drink packaging coating, and other. BPA is an endocrine disruptor compound that mimics the function of estrogen causing damage to reproductive organs. Bacterial degradation has been consider as a cost effective and eco-friendly method for BPA degradation compared with physical and chemical methods. This study aimed to isolate and identify bacterial strain capable to degrade and tolerate high concentrations of this pollutant, studying the factors affecting the degradation process and study the degradation mechanism of this strain. Results YC-AE1 is a Gram negative bacterial strain isolated from soil and identified as Pseudomonas putida by 16S rRNA gene sequence and BIOLOG identification system. This strain found to have a high capacity to degrade the endocrine disruptor Bisphenol A (BPA). Response surface methodology using central composite design was used to statistically optimize the environmental factors during BPA degradation and the results obtained by significant model were 7.2, 30 degrees C and 2.5% for optimum initial pH, temperature and inoculum size, respectively. Prolonged incubation period with low NaCl concentration improve the biodegradation of BPA. Analysis of variance (ANOVA) showed high coefficient of determination, R-2 and Adj-R-2 which were 0.9979 and 0.9935, respectively. Substrate analysis found that, strain YC-AE1 could degrade a wide variety of bisphenol A-related pollutants such as bisphenol B, bisphenol F, bisphenol S, Dibutyl phthalate, Diethylhexyl phthalate and Diethyl phthalate in varying proportion. Pseudomonas putida YC-AE1 showed high ability to degrade a wide range of BPA concentrations (0.5-1000 mg l(- 1)) with completely degradation for 500 mg l(- 1) within 72 h. Metabolic intermediates detected in this study by HPLC-MS were identified as 4,4-dihydroxy-alpha-methylstilbene, p-hydroxybenzaldeyde, p-hydroxyacetophenone, 4-hydroxyphenylacetate, 4-hydroxyphenacyl alcohol, 2,2-bis(4-hydroxyphenyl)-1-propanol, 1,2-bis(4-hydroxyphenyl)-2-propanol and 2,2-bis(4-hydroxyphenyl) propanoate. Conclusions This study reports Pseudomonas putida YC-AE1 as BPA biodegrader with high performance in degradation and tolerance to high BPA concentration. It exhibited strong degradation capacity and prominent adaptability towards a wide range of environmental conditions. Moreover, it degrades BPA in a short time via two different degradation pathways.

The application of the pre-validated pharmacophore 2-(2-oxazolinyl) aniline as an innate directing group in the C-H etherification and amination of nicotinamides for the efficient synthesis of drug-and agrochemical- like molecules was determined. An operationally simple, and regioselective C-H functionalization of nicotinamides was first accomplished using a complicated variation of copper salts. All the specific procedures used were easy to utilize, without external oxidants or ligands. The feasibility is highlighted using an alternative synthesis of diflufenican with a rapid synthesis of niacin related pharmaceuticals or analogues.
