, (2021/06/25)
PROBLEM TO BE SOLVED: To provide a method for producing a ketone derivative using a zinc derivative with high stability. SOLUTION: For example, a toluene solution of 6-decanethio-6-oxo hexanoic acid methyl and a 10% Pd/C-DMF suspension are added into a THF solution of phenyl pivalic acid zinc sequentially for a reaction, to synthesize 5-benzoylpentanoic acid methyl on the right side in the formula shown below.

Metal homoenolates are valuable synthetic intermediates which provide access to β-functionalized ketones. In this report, we disclose a Ni-catalyzed β-alkylation reaction of cyclopropanol-derived homoenolates using redox-active N-hydroxyphthalimide (NHPI) esters as the alkylating reagents. The reaction is compatible with 1°, 2°, and 3° NHPI esters. Mechanistic studies imply radical activation of the NHPI ester and 2e β-carbon elimination occurring on the cyclopropanol.

A series of [6,6]-phenyl-C61-butyric acid methyl ester (PCBM)-like fullerene derivatives with the butyl chain in PCBM changing from 3 to 7 carbon atoms, respectively (F1-F5), are designed and synthesized to investigate the relationship between
