We report a new, single-stage method for the synthesis of 2-arylpyrrolidines, based on an acid-catalyzed reaction of 2-naphthol with γ-ureidoacetals, enabling the preparation of the target compounds under mild conditions, while avoiding costly reagents and catalysts.

yields from a wide range of raw materials including amines (primaryamines and secondaryamines), carboxylic acids and isocyanates. Besides, an interesting reduction selectivity was observed. Exploration of the reaction process shows that it undergoes a two-step pathway via a formamide intermediate and the reduction of the formamide intermediate to monomethylamine as the rate-determining step.
