Base-induced cyclization of enantiopure (2-aminoalkyl)oxiranes allowed the stereospecific formation of pyrrolidin-3-ols and/or 2-(hydroxymethyl)azetidines, depending on the reaction conditions. The oxidation of 2-(hydroxymethyl)azetidines led to azetidine-2-carboxylic acids in high yields.
碱诱导的对映纯(2-氨基烷基)环氧乙烷的环化允许吡咯烷-3-醇和/或2-(羟甲基)氮杂环丁烷立体定向形成,这取决于反应条件。2-(羟甲基)氮杂环丁烷的氧化以高收率产生氮杂环丁烷-2-羧酸。
