Insertion into Donor–Acceptor Cyclopropanes with Carbon–Sulfur Moieties Derived from Sulfoxonium Ylides and Elemental Sulfur

Abstract The (3 + 2) cycloaddition of donor–acceptor cyclopropanes (DACs) with carbon–sulfur 2π components has become an emerging method to rapidly assemble tetrahydrothiophenes. Starting materials donating the carbon–sulfur unit are often isolated from thionation of carbonyls or...
