4-methyl aniline mediated method for the oxidativeC–C bond cleavage has been developed. The reaction proceeds in airusing molecular oxygen as the oxidant, affording one-carbon shortened esters in moderate to good yields within a short time. Moreover, it provides a model reaction for the highly enantioselective synthesis of (D)-serine esters by combining with a L-proline catalyzed Mannich reaction.

Allylationreactions of aldehydes and ketones occurred smoothly with indium metal in aqueousmedia. Compared to similar reactions with zinc and tin, the reaction with indium proceeds without the need of any promoter. The reaction can be extended to the synthesis of 2-methylene-γ-lactone 6 via the condensation of carbonyl compounds with 2-bromomethylacrylate 4.
