A new activating mode of donor–acceptor cyclopropane: the tug-of-war between strain and aromaticity, transient generation of quinone methides and their reactions with C-nucleophiles Open
Here, we present a new approach for activation of donor-acceptor cyclopropane systems in ring-opening reactions, which does not require the use of Lewis or Brønsted acid as a catalyst. Under treatment with a base, donor-acceptor cyclopropa…
