Synthetic routes to 3-acylpyrroles by methods involving ring closure, transformation of substituents, and further substitution of monosubstituted pyrroles were investigated. The condensation of H2NCHCHO with acylpyruvates appears to provide a general route to the 3-ketones. The related condensation of N-carbethoxyglycine ester and nitrile gave poor yields of 3-cyanopyrrole but attempts to obtain the 3-Ac derivative by the use of MeCOCH:CH2 showed the occurrence of an alternative reaction path and gave no useful product. Attempts to convert 3-cyano- and 3-carboxypyrroles into acyl derivatives by the action of nucleophilic reagents were not successful. Pyrrole-3-carboxaldehyde was obtained by decarboxylation of the minor formylation product of Et pyrrole-2-carboxylate. 24 references.
