  Stereocontrolled synthesis of C2-symmetric and pseudo-C2-symmetric diamino alcohols and diols for use in HIV protease inhibitors

  摘要：

  The stereocontrolled syntheses of dibenzyldiamino alcohol 1 and dibenzyldiamino diols 2-4, core units of potent C2-symmetric and pseudo-C2-symmetric inhibitors of HIV protease, are described, starting from phenylalanine. Stereoselective epoxidation of trans olefin 7, produced by S(N)2' displacement of an allylic mesylate, followed by regiospecific epoxide opening with lithium azide provided the azido alcohol 8 as the major product. Azide reduction and deprotection led to diamine 1. Protected diamino diols 15-17 were prepared expeditiously by intermolecular titanium- or vanadium-mediated pinacol coupling of protected phenylalaninal. Methods for the stereospecific interconversion of the major (3R,4R,5R,6S) isomer to the desired (3S,4R,5S,6S) isomer via intramolecular hydroxyl inversion are described.
