In 2022,Zhang, Qi; Shi, Mingying; Mi, Xueling; Luo, Sanzhong published an article in Organic Chemistry Frontiers. The title of the article was 《Catalytic asymmetric oxidative sulfenylation of β-ketocarbonyls using a chiral primary amine》.HPLC of Formula: 609-14-3 The author mentioned the following in the article:
Enantioselective oxidative construction of a C(sp3)-S bond has been achieved using a chiral primary amine catalyst in the presence of tert-Bu hydroperoxide and a catalytic amount of tetrabutylammonium iodide. The distinctive feature of the current reaction is coupling with nucleophilic sulfur reactants under oxidative conditions. This protocol provides facile access to chiral thioethers bearing S-containing quaternary stereocenters with good chemo- and enantiocontrol. The experimental process involved the reaction of Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3HPLC of Formula: 609-14-3)
Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3) belongs to ketone compounds. Ketones are highly reactive, although less so than aldehydes, to which they are closely related. Much of their chemical activity results from the nature of the carbonyl group. Ketones readily undergo a wide variety of chemical reactions.HPLC of Formula: 609-14-3
