Abstract: Regioselective synthesis of 1,1-bis(methylthio)-6-nitro-5-arylhex-1-en-3-one has been achieved from α-alkenoylketene dithioacetals with nitromethane using l-proline catalyst via Michael addition. The synthesized compounds 3a–j were well characterised by NMR and mass spectral techniques. One of the structures… read more here.
