An efficient annulation method for the synthesis of polysubstituted dihydrofurans I [R1 = H, Me, Bn, etc.] from 1,3-dicarbonyl compounds and maleimides was described. The reactions could afford furo[2,3-c]pyrrole derivatives with satisfactory yields. The developed strategy realized the direct oxidative double C(sp3)-H functionalization in the presence of copper(I) salts and 2-(tert-butylperoxy)-2-methylpropane. Meanwhile, this protocol featured a mild reaction condition and simple catalytic system. A reaction mechanism involving a single electron oxidation was also proposed. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3HPLC of Formula: 638-07-3).
Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.HPLC of Formula: 638-07-3
