  Synthesis of a Novel Series of Benzocycloalkene Derivatives as Melatonin Receptor Agonists

  摘要：

  We synthesized a novel series of benzocycloalkene derivatives and evaluated their binding affinities to melatonin receptors. To control the spatial position of the amide group, one of the important pharmacophores, we incorporated an endo double bond, an exo double bond (E- and Z-configurations), and a chiral center (R- and S-configurations) at position 1. The indan derivatives with the S-configuration at position 1 were the most promising in terms of potency and selectivity for the human melatonin receptor (MT, site), while compounds with the R-configuration showed little potential. Our next attempt was to investigate the most favorable conformation of the methoxy group, the other important pharmacophore for binding to the MT, receptor. The introduction of a methyl group at position 5 of the indene ring conserved affinity; however, at position 7, it caused a decrease in affinity. These results suggested that the substitution at position 7 forced the methoxy group to adopt an unfavorable orientation. The optimization of the condensed ring size and substituents led to (S)-8d [(S)-N-[2-(2,3-dihydro-6-methoxy-1H-inden-1-yl)ethyl]propionamide], which had high affinity for the human MT3 receptor (K-i = 0.041 nM) but no significant affinity for the hamster MT3 receptor (K-i = 3570 nM). In addition, a practical synthetic method of chiral N-[2-(2,3-dihydro-1H-inden-1-yl)ethyl]-alkanamides employing asymmetric hydrogenation with (S)-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl-Ru has been established.

  Racemic indan derivatives have been resolved by the hydrolysis of amide bonds using Corynebacterium ammoniagenes IFO12612 to produce (S)-amine and (R)-amides. In the kinetic resolution of 1 (N-[2-(6-methoxy-indan-1-yl)ethyl]acetamide), it was possible to run the reaction to 44% conversion on a 10-g scale, obtaining (S)-amine 4 ((S)-2-(6-methoxy-indan-1-yl)ethylamine) at >99% enantiomeric excess (ee) and (R)-1 at 98% ee.
