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.
公开了一种通过在至少一种酸的存在下使用至少一种过氧化物氧化3-吡咯烷衍生物(例如3,4-环氧吡咯烷,3-吡咯醇等)的方法。3-吡咯烷是通过从顺式-2-丁烯-1,4-二醇中派生顺式-2-丁烯化合物,并在顺式-2-丁烯衍生物和至少一种主要胺之间进行环化而产生的。该方法可以作为一锅合成进行,并且可以作为连续反应进行。
