Abstract
The incorporation of a sulfoxide on the tether connecting an alkene to a 5-silyloxy-4-pyrone diminishes the temperature needed for inducing their thermal [5C+2C] cycloaddition in relation to that required for a nnulating the homologous sulfide, and allows for attaining modest leve ls of diastereofacial selectivity.
