A novel synthesis of GSK1265744, a potent HIV integrase inhibitor, is described. The synthesis is highlighted by an efficient construction of the densely functionalized pyridinone core as well as a highly diastereoselective formation of the acyl oxazolidine moiety. The latter exploits the target molecule鈥檚 ability to chelate to Mg<sup>2+sup>, a key feature in the integrase inhibitor鈥檚 mechanism of action.
