  Asymmetric Synthesis of 9-Alkyl-2-benzyl-6,7-benzomorphans:  Characterization as Novel σ Receptor Ligands

  摘要：

  A convenient enantioselective synthesis of (1R,5R,9R)- and (1S,5S,9S)-9-alkyl-2-benzyl-6,7-benzomorphans (2a-c) which starts with naphthaldehyde is described. These compounds were designed to gain additional information on the structure-a binding relationship of the 6,7-benzomorphan class of a ligands. In contrast to pentazocine and most 6,7-benzomorphans, the (1R,5R,9R)-isomers of 2a-c showed greater affinity for the al receptor than the (1S,5S,9S)isomers. Despite reversal of enantioselectivity at the ax sites, moderate affinity and enantioselectivity at the sigma(2) sites [greater affinity for (1R,5R,9R)-isomers than (1S,5S,9S)-isomers] were maintained. A comparison of the binding affinities of 2a-e to the more conformationally flexible trans-2-alkyl-1-benzaminoethyl-1,2-dihydronaphthalenes (10a-c) suggested that the relatively rigid structure of 2a-c played an important part in their al binding properties. These compounds, particularly (1R,5R,SR)-2-benzyl-9-methyl-6,7-benzomorphan [(-)-2a], which has a Ki value of 0.96 nM, will be useful in further characterization of the al receptor.

  9-Alkyl 6,7-benzomorphans (1,2,3,4,5,6-hexahydro-11-alkyl-2,6-methano-3-benzazocines) are important selective ligands of sigma receptor sites; their asymmetric synthesis starting with (1R, 2R)- or (1S, 2S)-1-hydroxymethyl-2-alkyl-2-alkyl-1,2-dihydronaphthalene is described.
