Intramolecular annulations of donor–acceptor cyclopropanes
Abstract:
The intramolecular reaction of donor–acceptor cyclopropanes with various dipoles and dipolar equivalents allows access to a variety of bicyclic adducts with good stereocontrol. The linkers can often be cleaved to provide stereodefined products.
