A process is used for the preparation of 1,3,2-oxazaborolidine compounds. This process prepares compounds of formula (I) or (IA): in which: R1 is an alkyl or an aryl; and R2, R3, R4 and R5 are especially a hydrogen atom or an alkyl, wherein the following are reacted in two steps: a) a boric precursor compound with an acetal compound to give a boronate compound; and b) the boronate compound with an amino alcohol compound. This process avoids by-products and exhibits a very good stereospecificity.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 189028-93-1Related Products of 189028-93-1

Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Recommanded Product: (S)-1-(4-Fluorophenyl)-5-(2-oxo-4-phenyloxazolidin-3-yl)pentane-1,5-dione,

The S alcohol in the benzylic position of compound 2, a key feature of a novel cholesterol lowering agent Ezetimibe, was introduced by the (R)-MeCBS catalyzed asymmetric carbonyl reduction of ketone 1 using borane tetrahydrofuran complex (BTHF) as the reducing agent. The chemo- and enantioselectivity was dramatically enhanced by using an acid as a scavenger of the stabilizer sodium borohydride present in the commercially supplied pure BTHF. The effect of the critical reaction parameters such as addition mode of reagent, temperature, acids as well as water content on the selectivity has been examined. This reaction has been successfully applied in the commercial process for the preparation of the key intermediate 2 for Ezetimibe.

Introduction Exposure to pesticides has been associated with mental disorders, especially in occupationally exposed populations, such as farmers. This effect has been attributed to the neurotoxic and endocrine-disrupting activity of pesticides, as suggested by experimental studies. Objective To determine the prevalence of common mental disorders and self-reported depression, and analyze their association with the exposure to pesticides in a rural population resident in the municipality of Dom Feliciano, Rio Grande do Sul, where tobacco farming is the main economic activity. Methodology A cross-sectional study evaluating the prevalence of common mental disorders and self-reported depression in a sample of 869 adult individuals resident in Dom Feliciano, between October 2011 and March 2012 was performed. The evaluation of common mental disorders was performed using the Self-Reporting Questionnaire (SRQ-20), setting a cutoff point of 8 for both genders. A standardized questionnaire was used to obtain information on self-reported depression upon prior diagnosis by a health professional, and self-reported exposure to pesticide. In order to evaluate the association between exposure to pesticides and mental disorders, a non-conditional multivariate logistic regression analysis was performed. Results The prevalence of common mental disorders and self-reported depression in the sample population were 23% and 21%, respectively. Among individuals who reported depression, an increase of 73% was observed in the odds of pesticide exposure at an age equal to or less than 15 years. There was a positive association between self-reported pesticide poisoning and common mental disorders (OR = 2.63; 95% CI, 1.62-4.25) as well as self-reported depression (OR = 2.62; 95% CI, 1.63?4.21). Individuals who reported depression had a greater odds of exposure to pyrethroids (OR = 1.80; 95% CI, 1.01?3.21) and aliphatic alcohol (OR = 1.99; 95% CI, 1.04?3.83). An SRQ?20 ? 8 was associated with an approximately seven times higher odds of exposure to aliphatic alcohol (95% CI, 1.73?27.53). Self-reported depression positively correlated with a greater period of exposure to dinitroaniline (OR = 2.20; 95% CI, 1.03?4.70) and sulphonylurea (OR = 4.95; 95% CI, 1.06?23.04). Conclusion The results suggest that exposure to pesticides could be related mental disorders. However, other common risk factors in tobacco farming, the main local economic activity, cannot be excluded.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 1192-07-0 is helpful to your research. Reference of 1192-07-0

Cobalt(II)-catalyzed C(sp2)-O cross-coupling between aryl/heteroaryl alcohols and vinyl/aryl halides in the presence of CuI has been achieved under ligand-free conditions. In this reaction, copper plays a significant role in transmetalation rather than being directly involved in the C-O coupling. This unique Co/Cu-dual catalyst system provides an easy access to a library of aryl-vinyl, heteroaryl-styryl, aryl-aryl, and heteroaryl-heteroaryl ethers in the absence of any ligand or additive.

Chiral 1,4-dihydropyridines were prepared by the regio- and stereoselective addition of ketene silyl acetals and organometallic reagents to pyridinium salts. In the addition reaction, an intramolecular interaction between the thiocarbonyl or carbonyl with the pyridinium nucleus plays an important role in bringing about the selectivities. The absolute configuration of the newly produced stereogenic center of the 1,4-dihydropyridines was determined by X-ray analysis and CD Cotton effects after conversion into the appropriate derivatives. The working model for the stereoselectivity was proposed based on the ab initio calculations at the RHF/3-21G* level.
