• Highly Enantioselective Synthesis of Nitrocyclopropanes via Organocatalytic Conjugate Addition of Bromomalonate to α,β-Unsaturated Nitroalkenes

  Highly enantioselective synthesis of nitrocyclopropanes was achieved via the organocatalytic conjugate addition of dimethyl bromomalonate to nitroalkenes and the consequent intramolecular cyclopropanation. 6′-Demethyl quinine was found to be the efficient catalyst. Excellent enantioselectivities, diastereoselectivities, and good yields were obtained for a variety of aryl or heteroaryl nitroethylenes

  Synthetically useful nitrocyclopropanes are easily obtained via Michael addition of dimethyl bromomalonate to nitrostyrenes promoted by commercially available (S)-alpha,alpha-di-beta-naphthlyl-2-pyrrolidinemethanol as the catalyst, followed by DABCO-mediated intramolecular nucleophilic substitution. The functionalised nitrocyclopropanes are obtained in good yield, excellent diastereoselectivity and up to 49% ee. (C) 2010 Elsevier Ltd. All rights reserved.

  A novel one-pot methodology for the catalytic enantioselective synthesis of highly functionalized nitrocyclopropanes promoted by chiral nickel complexes is developed. The treatment of bromomalonates with nitroalkenes under the mild reaction conditions afforded the corresponding Michael adducts which cyclizes to controlled reaction conditions with excellent diasteroselectivities (>99 de) and enantioselectivities
