A simple and stereoselectivesynthesis of β-alkoxy- and β-alkylthio-acrylic esters and amides (8) by nucleophilic vinylic substitution of the tosyl group by sodium alcoholates and thiolates of (E)-β-tosylacrylic derivatives (7), prepared by iodosulfonylation-dehydroiodination of acrylic compounds, is described. This methodology is applied to the synthesis of sinharine (8eh) a natural antifungal isolated
