Synthesis of (−)-5,8-Dihydroxy-3R-methyl-2R-(dipropylamino)-1,2,3,4-tetrahydronaphthalene: An Inhibitor of β-Amyloid1–42 Aggregation
摘要:
A concise synthesis of the beta-amyloid(1-42) aggregation inhibitor (-)-5,8-dihydroxy-3R-methyl-2R-(dipropylamino)-1,2,3,4-tetrahydronaphthalene [(-)-2] has been developed. The key step is a regio- and diastereoselective hydroboration-amination sequence to convert alkene 6 into amine 9. Enantiomeric resolution was achieved by recrystallization of amine 9 as the dibenzoyl-D-tartaric acid salt. Hydroquinone 2 is a potent inhibitor of the fibrillar aggregation of beta-amyloid as determined in two different assay systems. (C) 2002 Elsevier Science Ltd. All rights reserved.
