Moritz, Jan-Ole published the artcileP-Chirogenic Diphosphazanes with Axially Chiral Substituents and Their Use in Rh-Catalyzed Asymmetric Hydrogenation, Synthetic Route of 617-52-7, the publication is Journal of Organic Chemistry (2020), 85(22), 14537-14544, database is CAplus and MEDLINE.
A convenient synthesis of enantiopure P-chirogenic diphosphazanes incorporating bulky bisphenol and 1,1′-bi-2-naphthol-derived substituents via the functionalization of a readily accessible enantiopure lithium phosphinoamide with chlorophosphoridites was developed. Since the product requires no subsequent deprotection, the protocol provides an easy, convenient synthesis of P-chirogenic ligands on the gram scale. The ligands were applied in the Rh-catalyzed asym. hydrogenation of benchmark substrates furnishing enantiomeric excess values up to 96%.
