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

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.

We report here the design, synthesis, and pharmacological properties of a series of compounds related to tranylcypromine (9), which itself was discovered as a lead compound in a high-throughput screening campaign. Starting from 9, which shows modest activity as a 5-HT2C agonist, a series of 1-aminomethyl-2-phenylcyclopropanes was investigated as 5-HT2C agonists through iterative structural modifications. Key pharmacophore feature of this new class of ligands is a 2-aminomethyl-trans-cyclopropyl side chain attached to a substituted benzene ring. Among the tested compounds, several were potent and efficacious 5-HT2C receptor agonists with selectivity over both 5-HT2A and 5-HT2B receptors in functional assays. The most promising compound is 37, with 120- and 14-fold selectivity over 5-HT2A and 5-HT2B, respectively (EC50 = 585, 65, and 4.8 nM at the 2A, 2B, and 2C subtypes, respectively). In animal studies, compound 37 (10-60 mg/kg) decreased immobility time in the mouse forced swim test.
