U. Appelberg et al., DERIVATIVES OF 2-ARYLCYCLOPROPYLAMINE - SYNTHESIS AND INTERACTIONS WITH 5-HT1A RECEPTORS, Bioorganic & medicinal chemistry letters, 6(4), 1996, pp. 415-420
A series of cis- and trans-derivatives of 2-aryl-N,N-dipropylcycloprop
ylamines and 1-(2-arylcyclopropyl)-N,N-dipropylmethylamines were synth
esized and evaluated for affinity at the 5-HT1A receptor. The key step
in the syntheses was a cyclopropanation of cis- and trans-3-arylprope
noic esters with diazomethane which proceeds with retention of the ste
reochemistry. Methoxyphenyl)cyclopropyl]-N,N-dipropylmethylamine (32)
had the highest 5-HT1A-receptor affinity (K-i = 58 nM) of the novel de
rivatives.
