Synthesis of chiral C/N-functionalized morpholine alcohols: Study of their catalytic ability as ligand in asymmetric diethylzinc addition to aldehyde

A broad variety of chiral C/N-functionalized morpholine alcohols sharing a common structural motif in the 3-(hydroxymethyl)morpholine 6 were prepared from enantiomerically pure serine for the purpose of studying their catalytic ligand properties. The asymmetric addition of diethylzinc to benzaldehyde in the presence of 10 mol % of chiral C/N-functionalized morpholine alcohols gave 1-phenyl-1-propanol in 59-81% yield with 10-30% ee. The addition of 10 mol % of n-butyl lithium to the reaction mixture resulted in a significant enhancement of the stereoselectivity in the case of ligands bearing the two geminal phenyl substituents on the backbone. In the presence of n-butyl lithium and using (S)-3-(hydroxydiphenylmethyl)morpholine (S)-19 as the chiral promoter, (S)-1-phenyl-1-propanol was obtained in 81% yield with 76% ee. The geminal diphenyl-class of morpholine ligands was examined for the diethylzinc addition to four different aldehydes in the presence of n-butyl lithium. (S)-N-Benzyl-3-(hydroxydiphenylmethyl)morpholine (S)-27 was found to be most enantioselective in the case of 4-methoxybenzaldehyde to give (R)-alcohol in 87% yield with 80% ee. Catalysts (S)-19 and its N-methyl derivative (S)-26 gave alcohols with an (S)-absolute configuration while the N-benzylated derivative (S)-27 gave the opposite enantiomeric products. The tentative transition state models to account for the observed product stereoselectivity with morpholine ligands holding the geminal diphenyl group on the beta-amino alcohol segment are proposed.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 95715-86-9 is helpful to your research. Electric Literature of 95715-86-9

Remote, Late-Stage Oxidation of Aliphatic C-H Bonds in Amide-Containing Molecules

Amide-containing molecules are ubiquitous in natural products, pharmaceuticals, and materials science. Due to their intermediate electron-richness, they are not amenable to any of the previously developed N-protection strategies known to enable remote aliphatic C-H oxidations. Using information gleaned from a systematic study of the main features that makes remote oxidations of amides in peptide settings possible, we developed an imidate salt protecting strategy that employs methyl trifluoromethanesulfonate as a reversible alkylating agent. The imidate salt strategy enables, for the first time, remote, nondirected, site-selective C(sp3)-H oxidation with Fe(PDP) and Fe(CF3PDP) catalysis in the presence of a broad scope of tertiary amides, anilide, 2-pyridone, and carbamate functionality. Secondary and primary amides can be masked as N-Ns amides to undergo remote oxidation. This novel imidate strategy facilitates late-stage oxidations in a broader scope of medicinally important molecules and may find use in other C-H oxidations and metal-mediated reactions that do not tolerate amide functionality.

Selective preparation of isomers and enantiomers of cyclopropane carboxylic acids

A process has been discovered for selective preparation of isomers and enantiomers of 2,2-dimethyl-3-(2,2-dihalovinyl)cyclopropane carboxylic acids. In this process an adduct of an alkyl 3,3-dimethyl-4-pentenoate and a substituted 2-oxazolidone is reacted with a substituted dihalomethane compound. The resulting compound is cyclized, dehydrohalogenated and hydrolyzed to yield the desired product. These cyclopropane carboxylic acids are useful precursors for pyrethroid insecticides.

History of antimicrobial drug discovery: Major classes and health impact

The introduction of antibiotics into clinical practice revolutionized the treatment and management of infectious diseases. Before the introduction of antibiotics, these diseases were the leading cause of morbidity and mortality in human populations. This review presents a brief history of discovery of the main antimicrobial classes (arsphenamines, beta-lactams, sulphonamides, polypeptides, aminoglycosides, tetracyclines, amphenicols, lipopeptides, macrolides, oxazolidinones, glycopeptides, streptogramins, ansamycins, quinolones, and lincosamides) that have changed the landscape of contemporary medicine. Given within a historical timeline context, the review discusses how the introduction of certain antimicrobial classes affected the morbidity and mortality rates due to bacterial infectious diseases in human populations. Problems of resistance to antibiotics of different classes are also extensively discussed.
