Stereoselective synthesis of functionalised cyclopropanes from nitroalkenes via an organocatalysed Michael-initiated ring-closure approach

Synthetically useful nitrocyclopropanes are easily obtained via Michael addition of dimethyl bromomalonate to nitrostyrenes promoted by commercially available (S)-α,α-di-β-naphthlyl-2-pyrrolidinemethanol as the catalyst, followed by DABCO-mediated intramo
