The synthesis of novel substituted pyrroloquinolinones is described by concomitant ring contraction cyclization form 2-(2-amino-5-nitro-phenyl)-[4 H ]-1,3-thiazines, which were derived from N -substituted 5-nitro-anthranilonitrile. An easy access to

The bielectronic electrochemical reduction of pyridazines, substituted by electron-withdrawing groups, leads to their corresponding 1,2-dihydro derivatives. Depending on the nature of the ring substitution, these intermediates can either rearrange in
