Conformationally restricted phenalene and acenaphthene derivatives 5 were synthesized from phenalen-1-one and acenaphthen-1-one derivatives using the Horner-Emmons reaction. The amines were prepared through the corresponding isocyanates by the Curtius reaction on the acids or by the reduction of the nitriles. Amido derivatives (R(3) = Me, Et, n-Pr, c-Pr)(More)
N-(4-Methoxy-2,3-dihydro-1H-phenalen-2-yl)amide derivatives, conformationally restricted ligands for melatonin receptors, were synthesized by an alternative synthetic method from the corresponding 1,8-naphthalic anhydride which was transformed into the phenalenecarboxylic acid 7. A Curtius reaction on 7 gave the amino compound which was acylated to give(More)
Naphthalene melatoninergic ligands with alkyl groups (Me, Et, Pr, Bz) in the beta position of the ethylamido chain were synthesised. The affinity of the compounds for chicken brain melatonin receptors was evaluated using 2-[125I]-iodomelatonin as the radioligand. An increase in the affinity was observed with the beta-methyl derivatives and the greatest(More)
