Synthesis and anion recognition properties of shape

Binol (1 1'-binaphthyl-2 2'-diol) based synthons are popular in the recent literature given their robustness they are frequently used to impart or transfer chiral information not only in the field of asymmetric synthesis and catalysis but also in materials science [19 –24] During the course of our ongoing efforts dealing with the use of binol-based synthons for the production of
