Synthesis of 6‐Substituted 7‐Bomoazabicyclo[2.2.1]heptanes via Nucleophilic Addition to 3‐Bromo‐1‐azoniatricyclo[2.2.1.0]‐heptane Bromide

We describe herein an efficient method for the preparation of a functionalised bicyclic framework (6‐substituted 7‐bromo‐aza‐bicyclo[2.2.1]heptane) through the selective opening of the aziridium 2 with organocuprates in up to 90% yield. These interesting chiral building blocks were then utilised as novel ligands in the rearrangement of epoxides to afford chiral allylic alcohols.
