A method for producing pyrrolidine derivatives such as 3,4-epoxypyrrolodines and 3-pyrrolidols comprises oxidizing 3-pyrrolines with at least one peroxide in the presence of at least one acid. The 3-pyrrolines are obtainable 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.
一种生产吡咯烷衍生物如 3,4-环氧吡咯烷和 3-吡咯烷醇的方法包括在至少一种酸存在下用至少一种过氧化物氧化 3-吡咯烷。通过从顺式-2-丁烯-1,4-二醇衍生出顺式-2-丁烯化合物,并在顺式-2-丁烯衍生物和至少一种伯胺之间进行环化反应,可获得 3-吡咯烷。该方法可作为一次合成进行,也可作为连续反应进行。
