A room-temperature (3+2) cycloaddition sequence for the synthesis of highly substituted dihydrothiophene derivatives has been developed. By utilizing structurally unique thiocarbonyl ylides, the reactivity of these traditionally high-energy intermediates can be modulated, enabling a synthetically useful transformation to proceed under mild conditions.
