In the present study we wish to report the details of the diastereoselective reactions of titanium enolates derived from N-propionyloxazolidone 1 in inter- and intramolecular Michael reactions with ethyl vinyl ketone, methyl acrylate, and acrylonitrile (eq 1).

By using designed biphenyl-2-ylphosphines functionalized with a remote basic groups as ligands, N-alkynyl-o-nosylamides are directly converted to (1E,3E)-1-amido-1,3-dienes with excellent diastereoselectivities under gold catalysis. With allenamides as substrates, the gold-catalyzed isomerizations are high yielding and applicable to a broad substrate scope including various nitrogen protecting groups and exhibit unprecedented (3E)-selectivities for the distal C-C double bond and good regioselectivities. Combining this gold catalysis with one-pot Diels-Alder reactions leads to rapid assembly of valuable bicyclic compounds.

Hydrosilane reduced alpha-oxy and alpha-amino ketones and beta-keto acid derivatives in trifluoroacetic acid to afford the corresponding erythro alcohols with high diastereoselectivity.The reaction proceeded without racemization at the carbon alpha to the carbonyl group.The erythro-directive reduction was explained in terms of the proton-bridged Cram cyclic model and successfully applied to the synthesis of physiologically important amino alcohols such as l-ephedrine, l-methoxamine, and erythro-2-methyl-3-piperidino-1-phenylpropanol.

A series of trans-4-phenylpyrrolidine-3-carboxamides were synthesized and characterized as potent ligands of the human melanocortin-4 receptor. Interestingly, a pair of diastereoisomers 20f-1 and 20f-2 displayed potent functional agonist and antagonist activity, respectively. Thus, the 3S,4R-compound 20f-1 possessed a Ki of 11 nM and an EC50 of 24 nM, while its 3R,4S-isomer 20f-2 exhibited a Ki of 8.6 and an IC50 of 65 nM. Both compounds were highly selective over other melanocortin receptor subtypes. The MC4R agonist 20f-1 also demonstrated efficacy in diet-induced obese rats.

497-25-6, Name is Oxazolidin-2-one, belongs to oxazolidine compound, is a common compound. SDS of cas: 497-25-6In an article, once mentioned the new application about 497-25-6.

Alkylative carboxylation of ynamides with CO2 and dialkylzinc reagents using a N-heterocyclic carbene (NHC)-copper catalyst has been developed. A variety of ynamides, both cyclic and acyclic, undergo this transformation under mild conditions to afford the corresponding alpha,beta-unsaturated carboxylic acids, which contain the alpha,beta-dehydroamino acid skeleton. The present alkylative carboxylation formally consists of Cu-catalyzed carbozincation of ynamides with dialkylzinc reagents with the subsequent nucleophilic carboxylation of the resulting alkenylzinc species with CO2. Dialkylzinc reagents bearing a beta-hydrogen atom such as Et2Zn and Bu2Zn still afford the alkylated products despite the potential for beta-hydride elimination. This protocol would be a desirable method for the synthesis of highly substituted alpha,beta- dehydroamino acid derivatives due to its high regio- and stereoselectivity, simple one-pot procedure, and its use of CO2 as a starting material. CO2 incorporation with alkylation: Alkylative carboxylation of ynamides with CO2 and a dialkylzinc reagent has been achieved by using a N-heterocyclic carbene (NHC)-copper complex as the catalyst. The reactions proceeded by Cu-catalyzed carbozincation of ynamides with dialkylzinc reagents and the subsequent carboxylation of the resulting alkenylzinc species (see scheme).

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: oxazolidine, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 102029-44-7, Name is (R)-4-Benzyl-2-oxazolidinone, molecular formula is C10H11NO2

In some cases, helical peptides stabilized by an i, i + 7 tether exhibit better target binding and cellular functions compared to their i, i + 4 analogues. Herein, we carried out a systematic study of the effects of an in-tether chiral center on the i, i + 7 system. We screened the optimal cross linking mode, tether length, in-tether chiral center positions, and absolute configurations. From these studies, we determined that a chiral center of R absolute configuration at the gamma-position to the C-terminal of a 10-membered tether could function to efficiently induce helicity of the backbone peptides. This is an important addition to the current i, i + 4 in-tether chiral center induced helicity strategy (CIH strategy), and could have broad biological applications.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C12H21NO4, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 147959-19-1, Name is (S)-tert-Butyl 2,2-dimethyl-4-(2-oxoethyl)oxazolidine-3-carboxylate, molecular formula is C12H21NO4

A novel and versatile strategy for the synthesis of heterocyclic alpha-amino acids has been described. The use of components (aldehyde or beta-ketoester) bearing a masked glycinyl moiety in Biginelli and Hantzsch cyclocondensations allowed access to the 4-dihydropyrimidinyl-alpha-glycines, 4-dihydropyrimidinyl-alpha-alanines, 4-pyridyl-alpha-alanines, and 2-pyridyl-alpha-alanines classes. Dihydropyrimidinylamino acids were obtained as a mixture of diastereoisomers due to the formation of the stereocenter at C4 of the dihydropyrimidinone ring. Individual stereoisomers were isolated as pure compounds and their structures were assigned with the aid of X-ray crystallography and chiroptical properties. The enantiomeric purity of a representative selection of the above amino acids was greater than 96% as verified by derivatization to the corresponding Mosher’s amides and subsequent 1H and 19F NMR spectroscopy. Incorporation of the 4-pyridyl-alpha-alanine derivative into a peptide chain is also described.
