Lu, Xi published the artcileNickel-catalyzed allylic defluorinative alkylation of trifluoromethyl alkenes with reductive decarboxylation of redox-active esters, Application of ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol, the publication is Chemical Science (2019), 10(3), 809-814, database is CAplus and MEDLINE.
An efficient method was developed for the synthesis of functionalized gem-difluoroalkenes I [R = c-hexyl, 4-BrC6H4(CH2)2, 4-CNC6H4O(CH2)2C(Me)2, etc.; Ar = 3,4-(OMe)2C6H3, 4-PhC6H4, 2-naphthyl, etc.] via nickel-catalyzed defluorinative reductive cross-coupling of trifluoromethyl alkenes with redox-active esters. The present reaction involved C(sp3)-F bond cleavage and C(sp3)-C(sp3) bond formation under very mild reaction conditions, while tolerating many sensitive functional groups and requiring minimal substrate protection. Therefore, this method provided an efficient and convenient approach for late-stage modification of biol. interesting mols.
