A synthesis of the pleuromutilin antibiotic SB-268091 is described which includes a new and improved route to the quinuclidine-4-thiol ligand. This chemistry has been run on multikilo scale and involved a reductive double debenzylation usingsodium in liquidammonia. Alternative conditions have been developed to prepare quinuclidine-4-thiol which avoid the use of sodium in liquidammonia. The generality
