A nitrogenous heterocyclic compound such as 3-aminopyrrolidine derivative is produced by hydrogenolysis of an N-substituted nitrogenous heterocyclic compound with normal pressure hydrogen in a water-based solvent in presence of a catalyst. In the case an optically active 1-substituted-3-aminopyrrrolidine derivative is used as a raw material, an optically active 3-aminopyrrolidine derivative can be obtained as a product practically without racemination.
A method for producing pyrrolidine derivatives such as 3,4-epoxypyrrolodines, 3-pyrrolidols and the like, by oxidizing 3-pyrrolines with at least one peroxide in the presence of at least one acid is disclosed. The 3-pyrrolines are produced by deriving cis-2-butene compounds from cis-2-butene-1,4-diols and performing a cyclization between the cis-2-butene derivatives and at least one primary amine. The method may be performed as a one-pot synthesis and may be performed as a continuous reaction.
