On the use of seven-membered phosphorous heterocycles based on 2,2′-dihydroxy-1,1′-binaphthalene and 1,4∶3,6-dianhydro-d-mannitol in the31P NMR analysis of the enantiomeric composition of chiral alcohols
摘要:
Some aspects of phosphorylation of 2,2'-dihydroxy-1,1'-binaphthalene (BINOL) and 1,4:3,6-dianhydro-D-mannitol (isomannide) were investigated. The possibility of using the corresponding cyclic chloro-and amidophosphites for the analysis of enantiomeric compositions of chiral primary and secondary alcohols by P-31 NMR was examined.
Fluorinative hydrolysis of phosphorothioic acid esters with a binaphthyl group through axis-to-center chirality transfer leading to the formation of P-chiral phosphorothioic monofluoridic acid salts
Asymmetric synthesis of P-chiral phosphorothioic monofluoridic acid ammonium salts was achieved via axis-to-center chirality transfer reactions by using phosphorothioicacid O-esters with a binaphthyl group, and the absolute stereochemistry of the salts was determined by X-ray analyses and by comparison of their CD spectra.
