Process for producing 1H-3-aminopyrrolidine and derivatives thereof

A process for producing 1H-3-aminopyrrolidine and derivatives thereof is disclosed. The process is especially useful for producing optically active 1H-3-aminopyrrolidine and derivatives thereof and in this case comprises reacting an optically active amino-protected aspartic anhydride represented by the formula (1) with a primary amine represented by the formula R'NH2, subjecting the reaction product to cyclodehydration to obtain an optically active 1-aralkyl-3-(protected amino)pyrrolidine-2,5-dione compound represented by the formula (2), subsequently eliminating the protective group from the 3-position amino group of the compound represented by the formula (2) to obtain an optically active 1-aralkyl-3-aminopyrrolidine-2,5-dione compound represented by the formula (3), reducing the carbonyl groups of the compound represented by the formula (3) to obtain either an optically active 1-aralkyl-3-aminopyrrolidine compound represented by the formula (4) or a salt thereof with a protonic acid, and then subjecting the compound represented by the formula (4) or the salt thereof to hydrogenolysis to obtain an optically active 1H-3-aminopyrrolidine or a protonic acid salt thereof.
