Trifluoromethyl Vinyl Sulfide: A Building Block for the Synthesis of CFS-Containing Isoxazolidines.

Trifluoromethyl vinyl sulfide, a potential building block for pharmaceutically and agrochemically relevant products, is prepared and used for the first time in high-pressure-mediated 1,3-dipolar cycloaddition reactions with nitrones to synthesize (trifluoromethyl)sulfanyl isoxazolidines.
