Method for synthesis of diphenylphosphinic acid was written by Luo, Mei. And the patent was published on February 15,2012.Application of 150699-08-4 The following contents are mentioned in the patent:
The title method comprises preparing 2-[(4R/S)-4,5-dihydro-4-R-2-oxazolinyl]phenol or 2-[(4R/S)-4,5-dihydro-4-R-2-oxazolinyl]aniline, reacting with diphenylphosphinyl chloride in toluene in the presence of triethylamine for 2 days, filtering, evaporating, carrying out chromatog. with petroleum ether-dichloromethane (1:9) as eluent and volatilizing to obtain diphenylphosphonic acid crystal. The yield is about 5%. This study involved multiple reactions and reactants, such as (R)-2-(4-Phenyl-4,5-dihydrooxazol-2-yl)phenol (cas: 150699-08-4Application of 150699-08-4).
(R)-2-(4-Phenyl-4,5-dihydrooxazol-2-yl)phenol (cas: 150699-08-4) belongs to oxazolidine derivatives. Oxazolidine-based compounds are well-known chiral auxiliaries and strategic molecular moieties in chemistry since they can effectively mask or mimic amino acid units or amino alcohols. As well as other multifunctional heterocyclic compounds, oxazolidine rings play an essential role in organic and medicinal chemistry, behaving, in some cases as powerful antitumor agents.Application of 150699-08-4
