Reactions of pyrrolidine with 2equiv of aldehydes without any catalyst in a pressurized vessel at 140–200°C yielded 1,3-disubstituted pyrroles. α-Branched aldehydes gave fairly good yields of the corresponding products by this method, which provides a facile non-oxidative procedure for synthesizing 1,3-dialkylpyrroles from inexpensive pyrrolidine and aldehydes.
