A novel asymmetric synthesis of 3-benzyl-1,2,3,4,5,6-hexahydro-11-alkyl-2,6-methano-3-benzazocines
Abstract
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.
