Formal Substitution of Bromocyclopropanes with Nitrogen Nucleophiles
摘要:
A highly chemo- and diastereoselective protocol toward amino-substituted donor acceptor cyclopropanes via the formal nucleophilic displacement in bromocyclopropanes is described. A wide range of N-nucleophiles, including carboxamides, sulfonamides, azoles, and anilines, can be efficiently employed in this transformation, providing expeditious access to stereochemically defined and densely functionalized cydopropylamine derivatives.

A chemo- and diastereoselective protocol for the formal nucleophilicsubstitution of 2-bromocyclopropylcarboxamides with secondary amides is described. This method allows for convergent and highly selective synthesis of trans-β-aminocyclopropane carboxylic acidderivatives.
