Enantioselective Organocatalyzed Michael Addition of Isobutyraldehyde to Maleimides in Aqueous Media

open access: yesMolecules, 2022
Thiourea was introduced into (R,R)-1,2-diphenylethylenediamine as an organocatalyst to promote the reaction between isobutyraldehydes and maleimides. Enantioselective Michael addition reaction was carried out as an eco-friendly method using water as the ...

Branched chain aldehydes: production and breakdown pathways and relevance for flavour in foods [PDF]

open access: yes, 2009
Branched aldehydes, such as 2-methyl propanal and 2- and 3-methyl butanal, are important flavour compounds in many food products, both fermented and non-fermented (heat-treated) products. The production and degradation of these aldehydes from amino acids

Polyoxometalate (POM)-layered double hydroxides (LDH) composite materials: design and catalytic applications [PDF]

open access: yes, 2017
Layered double hydroxides (LDHs) are an important large class of two-dimensional (2D) anionic lamellar materials that possess flexible modular structure, facile exchangeability of inter-lamellar guest anions and uniform distribution of metal cations in ...

Aldehydes are the predominant forces inducing DNA damage and inhibiting DNA repair in tobacco smoke carcinogenesis

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance Tobacco smoke (TS) contains numerous carcinogens. Intriguingly, while TS itself is a weak carcinogen in animal models, many of the TS components, such as 4-(methylnitrosamine)-1-(3-pyridyl)-1-butanone (NNK) and polycyclic aromatic ...
