Abstract
The first example of Nd@C3N4-photoredox/chlorine dual catalyzed alkylation with unactivated alkanes as the alkyl sources has been developed, which allows for the synthesis of various 4-alkylated cyclic sulfonyl ketimines. In this process, chlorine functions as both a redox and hydrogen atom transfer catalyst. The synergism of the reversible Nd2+/Nd3+ and Cl¯/Cl˙ redox pairs significantly enhances overall photocatalytic efficiency. The in vitro anticancer activity of 4-alkylated products was evaluated by using the CCK8 assay against both human choroidal melanoma (MUM-2B) and lung cancer (A549) cell. Compound 3da showed approximately triple the potency of 5-fluorouracil.
