A novel, efficient route to biologically and pharmaceutically important o-(dimethylamino)aryl ketones, acridones, acridinium salts, and 1H-indazoles has been developed starting from readily available hydrazones of aldehydes and o-(trimethylsilyl)aryl triflates. The reaction proceeds through arynes under mild conditions, tolerates a wide range of functional groups, and provides the final products in
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.
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
