Research and Development of an Efficient Synthesis of Hexahydrofuro[2,3-b]furan-3-ol Moiety—A Key Component of the HIV Protease Inhibitor Candidates
摘要:
A highly efficient method for synthesizing racemic hexahydrofuro[2,3-b]furan-3-ol has been developed utilizing a lanthanide catalyst, such as Yb(fod)(3), to promote condensation of 2,3-dihydrofuran and glycolaldehyde dimer. Access to either optically enriched enantiomer of bisfuran alcohol can be obtained by using this method employing chiral ligands with the lanthanide catalyst. In support of Gilead Sciences' protease inhibitor project, this method has been demonstrated to be a robust and scalable process with potential application for the construction of a variety of furo[2,3-b]furan derivatives.

Design and synthesis of nonpeptidal bis-tetrahydrofuran ligands based upon the X-ray crystal structure of the HIV-1 protease-inhibitor complex 1 led to replacement of two amide bonds and a 10 pi-aromatic system of Ro 31-8959 class of HIV proteaseinhibitors. Detailed structure-activity studies have now established that the position of ring oxygens, ring size, and stereochemistry are all crucial to
