2-Phospha[3]ferrocenophanes with planar chirality: synthesis and use in enantioselective organocatalytic [3 + 2] cyclizations.

Abstract

Planar chiral phosphines displaying a new ferrocenophane scaffold have been prepared via a stereoselective approach. The P-cyclohexyl substituted phosphine affords high levels of asymmetric induction in the organocatalytic [3 + 2] annulation reaction between allenes and electron-poor olefins.
