Li, Shichao; Hou, Bo; Wang, Jianbo published their research in Journal of Organic Chemistry in 2021. The article was titled 《Palladium-Catalyzed Oxidative Coupling of the Allenic C-H Bond with α-Diazo Esters: Synthesis of [3]Dendralenes》.Formula: C7H12O3 The article contains the following contents:
A palladium-catalyzed highly regio- and stereoselective C-H oxidative coupling of allenes such as I with α-diazo esters such as benzyl 2-diazopropanoate is developed. The reaction pathway involves allylic palladium carbene as the key intermediate, which is followed by a carbene migratory insertion process. The reaction proceeds efficiently under mild conditions without external base, providing substituted [3]dendralenes such as II bearing various functional groups. After reading the article, we found that the author used Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3Formula: C7H12O3)
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.Formula: C7H12O3
