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.

The regioisomeric composition of the adducts of unsymmetrical oxiranes with achiral and chiral phosphorochloridites was studied. Factors allowing enantiomeric assessment of chiral oxiranes with the aid of chiral derivatizing organophosphorus reagents were revealed.
