In 2019.0 BEILSTEIN J ORG CHEM published article about LIGANDS; HYDROGENATION; STEREOSELECTIVITY; PHOSPHINES; OXIDATION; ALCOHOLS; ACID in [Kmieciak, Anna; Krzeminski, Marek P.] Nicolaus Copernicus Univ Torun, Fac Chem, 7 Gagarin St, PL-87100 Torun, Poland in 2019.0, Cited 30.0. The Name is 4-Nitrobenzoic acid. Through research, I have a further understanding and discovery of 62-23-7. HPLC of Formula: C7H5NO4
New chiral regioisomeric gamma-hydroxyphosphine ligands were synthesized from alpha-pinene. The key transformation was the thermal [2,3]-sigmatropic rearrangement of allyldiphenylphosphinites, obtained from (1R,2R,4S,5R)-3-methyleneneoisoverbanol and (1R,2R,3R,5R)-4-methyleneneoisopinocampheol, to allylphosphine oxides. Hydroxy groups were introduced stereoselectively through a hydroboration-oxidation reaction proceeding from the less hindered site providing a trans relationship between the hydroxy and the phosphine substituents.
