A new synthesis of pyrroles
Quiclet-Sire, Beatrice,Wendeborn, Frederique,Zard, Samir Z.
, p. 2214 - 2215 (2002)
The radical reaction between an N-ethylsulfonylenamide and an α-xanthyl ketone gives an intermediate γ-keto imine which spontaneously ring-closes to the pyrrole.
The application of vinylogous iminium salts and related synthons to the regiocontrolled preparation of 2,3- and 2,5-disubstituted pyrroles
Gupton, John T.,Petrich, Scott A.,Smith, Lana L.,Bruce, Marc A.,Vu, Phong,Du, Karen X.,Dueno, Eric E.,Jones, Claude R.,Sikorski, James A.
, p. 6879 - 6892 (2007/10/03)
The reaction of 1-substituted vinamidinium salts with sarcosine ethyl ester produced 2,3-disubstituted pyrroles; a similar reaction with glycine ethyl ester gave 2,5-disubstituted pyrroles. Reactions of related three-carbon synthons with sarcosine and gly

Ezquerra, Jesus,Pedregal, Concepcion,Rubio, Almudena,Valenciano, Jesus,Garcia Navio, Jose Luis,Alvarez-Builla, Julio,Vaquero, Juan Jose
, p. 6317 - 6320 (2007/10/02)
5-Arylpyrrole-2-carboxylic acids are prepared by DDQ oxidative aromatization of the corresponding ethyl 2-aryl-Δ1-pyrroline-5-carboxylate followed by basic hydrolysis.
An Efficient, Regiocontrolled Synthesis of 5-Aryl-2-carbethoxypyrroles from 3-Aryl-3-chloropropeniminium Salts
Gupton, John T.,Krolikowski, Dale A.,Yu, Richard H.,Vu, Phong,Sirkorski, James A.,et al.
, p. 5480 - 5483 (2007/10/02)
A variety of 3-aryl-3-chloropropeniminium salts react with α-amino acid esters under basic conditions to produce 2-carbethoxy-5-arylpyrroles in a regioselective manner.The overall process represents a short, efficient, and convergent synthesis of 2,5-disu
