Abstract
A concise and efficient synthesis of (3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-ol, a key building block for several clinical and experimental HIV protease inhibitors including the highly important drug darunavir, was achieved via a one-pot procedure using furan and Cbz-protected glycol aldehyde as starting materials. A [2+2]-photocycloaddition between both reactants which can be prepared from wood-based starting materials according to the principles of xylochemistry, followed by hydrogenation and lipase-catalyzed kinetic resolution afforded the target compound in high yield and up to 99% ee.
