Lewis‐Acid‐Catalyzed (3+2)‐Cycloadditions of Donor‐Acceptor Cyclopropanes with Thioketenes

The reactivity of donor‐acceptor (D‐A) cyclopropanes towards thioketenes was investigated. In a (3+2)‐cycloaddition using Sc(OTf)3 as a Lewis acidic catalyst, the corresponding exocyclic thioenol ethers (2‐methylidene tetrahydrothiophenes) were formed in moderate to good yields. Unsymmetrical thioke...
