Templated assembly of medium cyclic ethers: Via exo-trig nucleophilic cyclization of cyclopropenes
A novel method for the assembly of medium heterocycles via an intramolecular nucleophilic addition to cyclopropenes generated in situ from the corresponding bromocyclopropanes is described. The exo-trig nucleophilic cyclizations were shown to proceed very efficiently and in a highly diastereoselecti...
