    Description / Table of Contents: Reactions of Pyrroles with α,β-Unsaturated Aldehydes and KetonesReactions of α,β-unsaturated aldehydes and ketones with pyrrole derivatives yields the (3-oxoalkyl)pyrroles2, 6, and7 as well as the tris(pyrrolyl)propanes3 and4. Compound3a is oxidized to give the tripyrryltrimethine5 and the dipyrryltrimethine1a, respectively. The Bucherer hydantoin reaction is recognized to be suitable for the characterization of (3-oxoalkyl)pyrroles.
