Abstract

A study was carried out on the reaction of chiral benzodioxane, benzofuran, and thiazole derivatives of isoflavone with various lanthanide shift reagents (LSR). The PMR shifts depend on the LSR used, while detection of chirality for these compounds using chiral LSR was difficult. Lowering the temperature and adding Yb(FOD)3 may enhance the splitting of the PMR signals of chiral molecules in the presence of LSR.
