A General Method for the Preparation of 2-Benzylpyrroles by Modified Borohydride Reduction of Azafulvenium Salts

2-Benzylpyrroles (5a-h) can be prepared in high yield from pyrroles by reduction, with modified borohydride reagents, of the corresponding 1-azafulvenium salts (3a-h) generated in situ in the presence of excess of phosphoryl trichloride.The procedure is compatible with ester groups.
