Enamides have first been prepared by reaction of 5-methoxy-3-chromanone and 2-tetralone with primary amides under acidic conditions. The enantioselectivities observed in the asymmetric hydrogenation of these enamides using ruthenium catalysts strongly dep

A series of unsubstituted and methoxy-substituted 2-amidotetralins (4a-q) was prepared and evaluated for their ability to complete for 2-iodomelatonin binding to chicken retinal membranes and for their potency to inhibit the calcium-dependent release of dopamine from rabbit retina.The lead compound, 2-acetamido-8-methoxytetralin (4j), showed a moderate affinity (Ki = 46 nM) and potency (IC50 = 1.4 nM) at the melatonin receptor.The structural requirements necessary for optimal agonistic activity at the melatonin receptor are as follows.First, the amido group, which should have a small, nonbranched alkyl group, is essential for affinity, and second, the methoxy substituent at the 8-position of the 2-amidotetralin ring is essential for optimal agonistic activity at the melatonin receptor.We concluded that this series of unsubstituted and methoxy-substituted 2-amidotetralins constitutes a class of nonindolic melatonin-like agents that can be used as pharmacological tools to further characterize melatonin receptors and to elucidate the mode of action of melatonin.
