Page/Page column 8, (2008/06/13)
Compositions for the oxidative dyeing of keratin fibers, comprising a medium suitable for dyeing and at least one bicyclic 5-6 systems of aza heteroaromatic keratin dyeing compounds wherein the 5-membered rings have one to three nitrogen atoms and an N-hydroxy or N-amino group and derivatives thereof. A method for oxidative dyeing of keratin fibers, comprising applying such compositions in the presence of an oxidizing agent, for a period sufficient to develop the desired coloration.

The development of enhanced conditions for Lewis acid catalysed Leimgruber-Batcho indole synthesis using microwave acceleration is described. This approach has permitted the preparation of a variety of heteroaromatic enamine intermediates in good yield and high purities. Subsequent catalytic hydrogenation reactions, under various conditions including the use of a solid-phase encapsulated catalyst, furnish the corresponding indole derivatives in good yields.
