Synthetic Studies on Chromone Natural Products: The Preusso­chromones

Abstract

AbstractTotal syntheses of preussochromones A, D, E, and F and structural revisions of preussochromones E and F are reviewed, demonstrating the use of α-keto esters and α,β-diketo esters as valuable reactants in stereoselective cyclization reactions in total synthesis.1 Introduction2 The Route to Preussochromone D3 Synthesis and Structural Revision of Preussochromones E and F4 Total Synthesis of Preussochromone A5 Conclusion
