The carbon–carbon bond-forming method in aqueousmedia was investigated by using indium as a single-electron transfer radical initiator. The indium-mediated intermolecular alkylradicaladdition to imine derivatives and electron-deficient CCbond proceeded effectively.

Indium-Mediated Intermolecular Alkyl Radical Addition to Electron-Deficient CN Bond and CC Bond in Water
see text] The intermolecular alkylradicaladdition to imine derivatives was studied in aqueousmedia by using indium as a single-electron-transfer radical initiator. The one-pot reaction based on radicaladdition to glyoxylic hydrazone provided a convenient method for preparing the alpha-amino acids. The indium-mediated radicaladdition to an electron-deficient C=Cbond also proceeded effectively to
glyoxylic imines was studied using zinc dust as a radical initiator. The zinc-mediated radical reaction of glyoxylic oximeethers and hydrazones proceeded smoothly to give the alkylated products via a carbon-carbon bond-forming process in aqueous media. The reaction of the oximeethers and hydrazones having an Oppolzer's camphorsultam group provided the corresponding alkylated products, which could be converted
