Asymmetric Phospha‐Diels–Alder Reaction: A Stereoselective Approach towards P‐Chiral Phosphanes through Diastereotopic Face Differentiation

Abstract

Old principles, new chemistry: a facile stereoselective synthesis of P-chiral phosphanes is described in which the principle of enantiotopic and diastereotopic face differentiation used in carbon chemistry is extended to a phosphorus atom in a planar environment, that is, 2H-phospholes.
