Synthesis of 5-(1-Alkoxyalkylidene)tetronates by Direct Condensation Reactions of Tetronates with Thionolactones and Thionoesters
We report a two-step approach to bicyclic and monocyclic 5-(1-alkoxyalkylidene)tetronates starting from lactones/esters. The method features the use of thionolactones and thionoesters as activated forms of lactones/esters that allows the direct condensati
