, p. 2133 - 2136 (2003)
An efficient one-step synthesis of 4-nitro-N-aryl substituted glutarimides, succinimides and maleimides in polyphosphoric acid is described together with the subsequent reduction to the corresponding anilines. The scope and limitation of this cyclocondensation are presented.

Page/Page column 20; 21, (2017/08/26)
A process for synthesizing 2-methoxymethyl-l,4-benzenediamines which comprises a radical halogenation step of compounds of formula (II) to compounds of formula (III). The final product can be 2-methoxymethyl-l,4-benzenediamine useful as coupler or primary intermediate in compositions for dyeing keratin fibers.

The dienamine products formed by the reaction between polysubstituted succinimides and the Petasis reagent were subjected to isomerization under mild acidic conditions to give polysubstituted pyrroles in excellent yields (85-95%). The scope and limitations of this methodology are explored.
