Description

Methyl-4-oxobutyrate is a kind of oxobutyrate derivative. It is an important industrial intermediate. It, together with its methanol addition products such as methyl 4,4-dimethoxybutyrate and gamma- methoxy-gamma-butyrolactone are useful intermediates during the preparation of some important industrial compounds such as gamma- butyrolactone, 1,4-butanediol and glutamate. It is also useful as a model substrate during exploring the asymmetric henry reaction since it can assemble a stereodefined lactam with high efficiency and enantiomeric purity.

Uses

Methyl 4-oxobutanoate may be used as a starting material to synthesize (-)-deoxoprosophylline, a piperidine alkaloid with therapeutic potential.

Check Digit Verification of cas no

The CAS Registry Mumber 13865-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,6 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13865-19:
(7*1)+(6*3)+(5*8)+(4*6)+(3*5)+(2*1)+(1*9)=115
115 % 10 = 5
So 13865-19-5 is a valid CAS Registry Number.

Asymmetric one-pot synthesis of five- and six-membered lactones via dynamic covalent kinetic resolution: Exploring the regio- and stereoselectivities of lipase

Xu, Jintao,Hu, Lei

, p. 868 - 871 (2019)

Cascade lipase-catalyzed lactonization has been applied to dynamic hemithioacetal formation, leading to efficient five- and six-membered lactone synthesis as well as chiral discrimination. Solvent-dependent regioselectivity was observed for the selective formation of 1,3-oxathiolan-5-one and γ-butyrolactone derivatives.

STEREOSPECIFIC CONSTRUCTION OF EXO-TETRASUBSTITUTED OLEFINS. THE EFFICIENT SYNTHESIS OF CYANO-CARBACYCLINS

Shibasaki, Masakatsu,Sodeoka, Mikiko

, p. 3491 - 3494 (1985)

Cyano-carbacyclins (2 and 3) were efficiently sythesized using the stereospecific 1,4-hydrogenation of the corresponding conjugated diene 10a catalyzed by the arene.Cr(CO)3 complex as a key step.

A new, highly selective, water-soluble rhodium catalyst for methyl acrylate hydroformylation

Fremy, Georges,Castanet, Yves,Grzybek, Ryszard,Minflier, Eric,Mortreux, Andre,et al.

, p. 11 - 16 (1995)

Hydroformylation of methylacrylate to α-aldehyde can be achieved in a two-phase system in the presence of two new water-soluble phosphines.High yields and selectivities of α-aldehyde (ca. 80percent with a α/β ratio of 1:20) were obtained.Spectroscopic studies have been carried out and some new rhodium complexes formed in situ in catalytic systems have been identified.Keywords: Hydroformylation; Methyl acrylate; Water-soluble phosphines; Rhodium; Catalysis; Two phase system

New Reagents for the Regiospecific Synthesis of Naturally Occurring Quinizarins

Simoneau, Bruno,Savard, Jacques,Brassard, Paul

, p. 5433 - 5434 (1985)

A modified Nef reaction applied to 4-nitrobutanoates gives the corresponding acetals which after hydrolysis and enol silylation yield the new 1,3-dienes 1-methoxy-1,4-bis(trimethylsiloxy)butadiene and its 3-methyl derivative.The latter reacts smoothly with chloronaphthoquinones and provides simple and efficient syntheses of 2-methylquinizarin, islandicin, digitopurpone, and erythroglaucin.

Catalyst composition containing bidentate phosphine ligand and application thereof

-

Paragraph 0068; 0089-0092, (2021/11/03)

The catalyst composition comprises a bidentate phosphine ligand and a rhodium complex, wherein the skeleton of the bidentate phosphine ligand not only has C. 2 The symmetry and the appropriate rigidity, and the phosphine ligand derived based on the skeleton can provide effective steric hindrance around the catalyst center metal, so that the selectivity of the catalyst can be remarkably improved, the aldehyde yield is not lower 92% when the catalyst combination is applied to the hydroformylation reaction, and the selectivity of n-aldehyde is not lower 90%. In addition, the raw materials olefins with different structures can obtain outstanding reaction rate and normal aldehyde selectivity as compared with the existing catalyst systems, and can be suitable for the hydroformylation reaction of more types of olefins.

Total Synthesis of DHA and DPA n-3Non-Enzymatic Oxylipins

Bultel-Poncé, Valérie,Degrange, Thomas,Durand, Thierry,Galano, Jean-Marie,Guy, Alexandre,Merad, Jérémy,Oger, Camille,Reversat, Guillaume

, (2021/12/02)

Oxylipins are formed in vivo from polyunsaturated fatty acids (PUFAs). A large structural variety of compounds is grouped under the term oxylipins, which differ from their formation mechanism (involving enzymes or not), as well as their chemical structures (cyclopentane, tetrahydrofuran, hydroxylated-PUFA, etc.). All structures of oxylipins are of great biological interest. Directly correlated to oxidative stress phenomenon, non-enzymatic oxylipins are used as systemic and/or specific biomarkers in various pathologies, and more especially, they were found to have their own biological properties. Produced in vivo as a non-separable mixture of isomers, their total synthesis is a keystone to answer biological questions. In this work, the total synthesis of three non-enzymatic oxylipins derived from docosahexaenoic acid (DHA) and docosapentanoic acid (DPAn-3) is described using a unique and convergent synthetic strategy.
