Abstract

A new class of cyclohexane-based P, N-ligands is readily obtained through aziridine ring opening with suitable phosphorus nucleophiles under acidic conditions. trans-1-Amino-2- diphenylphosphinocyclohexane is resolved with tartaric acid to give the final product in> 99% ee. The new ligands show high stability toward oxidation at the phosphorus atom.
