Benzannulation of 3-substituted pyrroles to indoles
Katritzky, Alan R.,Ledoux, Stephane,Nair, Satheesh K.
, p. 5728 - 5730 (2003)
In a new general indole synthesis, the anion derived from benzotriazolyl derivative 5b underwent regioselective 1,4-addition to various α,β-unsaturated ketones; subsequent acid-catalyzed cyclization formed the corresponding indoles 1a-f.
Synthesis and Diels-Alder reactions of the furo[3,4-b]pyrrole ring system. A new indole ring synthesis
Moskalev, Nikolai V.,Gribble, Gordon W.
, p. 197 - 201 (2007/10/03)
The previously unknown furo[3,4-b]pyrrole ring system has been synthesized from the appropriate pyrrolo hydroxyketones by acid-catalyzed cyclodehydration. Diels-Alder reactions of these furo[3,4-b]pyrroles affords a new synthesis of indoles.
