Quizon-Colquitt, Desiree M.,Lash, Timothy D.
, p. 477 - 482 (2007/10/02)
Cyclopentanone condensed with phenylhydrazones 5, or oximes 6, in the presence of zinc dust, sodium propionate and propionic acid at 150 deg C to give cyclopentapyrroles 7 in good yields.This chemistry was extended to the synthesis of pyrrolic products
The Synthesis and Chemistry of Azolenines. Part 2. A General Synthesis of Pyrrole-2-carboxylic Acid Derivatives by the Reaction of 2H-Azirines with Enamines, and the Crystal and Molecular Structure of Ethyl 3-Phenyl-4,5,6,7-tetrahydroindole-2-carboxylate
Law, Kam Wah,Lai, Ting-Fong,Sammes, Michael P.,Katritzky, Alan R.,Mak, Thomas C.W.
, p. 111 - 118 (2007/10/02)
A new general synthesis of 1H-pyrrole-2-carboxylic acid derivatives is described.Reaction between appropriately substituted 2H-azirines and enamines gives a mixture of 2,3- and 3,4-dihydropyrroles, which on acid treatment yields the title compounds in mod
