A general practical asymmetric synthesis of (1S,2R)-(+)-5-methoxyl-1-methyl-2-(di-n-propylamino)tetralin hydrochloride (UH-232) was developed in a short and efficient method in high optical purity starting from commercially available 5-methoxy-1-tetralone. Asymmetric hydroboration of 5-methoxy-1-methyl-3,4-dihydronaphthalene with monoisopinocampheylborane followed by treatment with NaOH/H2O2 afforded key intermediate tetrahydronaphthol 4. Compound 4 was converted to the target molecule 1 using straightforward reactions. (C) 1999 Elsevier Science Ltd. All rights reserved.
