The 3-alkyl-4,5,6,7-tetrahydroindoles 4a and 4b reacted with lead tetraacetate in acetic acid to give the corresponding 7-acetoxy derivatives; hydrolysis, followed by treatment with potassium ferricyanide in refluxing acetic acid afforded the novel porphyrins 6a and 6b.
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

, 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
