Better than all the rest: Tertiary boronic esters, readily available using the lithiation–borylation reaction, have been converted into tertiary alkylamines in very high ee. The work has been applied to a short, modular, and fully stereocontrolled synthesis of the pharmaceutical igmesine and chiral 2,2‐disubstituted piperidines.
优于所有其他化合物:叔硼酸酯(使用锂化-硼化反应可轻松获得)已在非常高的ee中转化为叔烷基胺。这项工作已被应用于药物艾美辛和手性2,2-二取代哌啶的简短,模块化和完全立体控制的合成。
