A good promoter: A convenient method is described for the generation and reaction of the enolates of aminoacetone equivalents, which uses the reduction of azetidin‐3‐one with titanium tetraiodide and subsequent reactions with electrophiles. This methodology provides a straightforward access to 1,4‐amino alcohols or diamines in a regioselective manner.
良好的促进剂:描述了一种方便的方法来生成和反应氨基丙酮当量的烯醇化物,该方法使用四碘化钛还原氮杂环丁烷-3-酮,然后与亲电试剂反应。这种方法可以以区域选择性的方式直接访问1,4-氨基醇或二胺。
