Han, Chunyu; Tian, Xianhai; Zhang, Huili; Rominger, Frank; Hashmi, A. Stephen K. published an article in Organic Letters. The title of the article was 《Tetrasubstituted 1,3-Enynes by Gold-Catalyzed Direct C(sp2)-H Alkynylation of Acceptor-Substituted Enamines》.HPLC of Formula: 30414-53-0 The author mentioned the following in the article:
A gold-catalyzed synthesis of tetrasubstituted 1,3-enynes from hypervalent iodine(III) reagents and activated alkenes is reported. This reaction involves an in situ formed alkynyl Au(III) species and a subsequent direct C(sp2)-H functionalization of alkenes, offering 26 enynes in 62-92% yield with excellent functional group tolerance. In the experiment, the researchers used many compounds, for example, Methyl 3-oxovalerate(cas: 30414-53-0HPLC of Formula: 30414-53-0)
Methyl 3-oxovalerate(cas: 30414-53-0) belongs to ketone compounds. Ketone compounds have important physiological properties. They are found in several sugars and in compounds for medicinal use, including natural and synthetic steroid hormones. Molecules of the anti-inflammatory agent cortisone contain three ketone groups.HPLC of Formula: 30414-53-0
