The efficient synthesis of (3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-ol and its isomers
摘要:
The stereoselective synthesis of all the possible stereoisomers of bis-tetrahydrofyran alcohol, a ligand used for obtaining HIV protease inhibitors including Darunavir 1 and Brecanavir 2 has been achieved. A key intermediate 4-pentenal 5 was obtained by employing a Wittig olefination-Claisen rearrangement protocol from D-glyceraldehyde derivative 3 as a source of chirality. The 4-pentenal was readily converted in the bis-THF alcohol moiety in three steps. (C) 2010 Elsevier Ltd. All rights reserved.
