Abstract

The first highly diastereoselective (dr up to > 95:5) hydrophosphonylationof heterocyclic imines by a chiral phosphorus nucleophile is introduced. Addition of binaphthol ester of phosphorus acid towards BF3-activated 3-thiazolines gives the corresponding (aR*,4R*)-4-thiazolidinylphosphonates almost exclusively as elucidated by X-ray analysis.
