developed the first catalytic enantioselective synthesis of sulfonium ylides with a chiral sulfur center. They are constructed from a broad array of sulfides in high yields (up to 98%) and enantioselectivities (up to 99%) through copper-catalyzed intramolecular carbene transfer reaction. The obtained ylides could be converted into alkylidenecyclopropanes with efficient sulfur-to-carbon chirality transfer.
