For the first time cyclopropyltrifluoroborates have been utilized to form cyclopropylamines in a one-pot procedure. The scope was not only demonstrated by successfully reacting various racemic cis- and trans-2-substituted cyclopropanes as well as azides, but also by applying the sequence to enantiomericallypure building blocks. An approach to tranylcypromine as well as belactosin A is outlined.
环丙基三氟硼酸盐首次用于在一锅法中形成环丙胺。该范围不仅通过各种外消旋顺式和反式 2- 取代环丙烷以及叠氮化物的成功反应来证明,而且还通过将序列应用于对映体纯构建块来证明。概述了反苯环丙胺和 belactosin A 的方法。

Cyclopropylamines are versatile intermediates and products both in organic synthesis in general and for active substances in particular. Although the synthesis of the corresponding enantiomericallypurecyclopropylboronicesters had been established previously, the C–B to C–N transformation was elusive. A detailed study directed towards the synthesis of several enantiomericallypure cyclopropylamines
