APPLICATIONS
The bi-naphthyl structure serves as an important ligand for asymmetric synthesis in organic chemistry, especially in Diels-Alder reactions, carbonyl addition and reductions.
Some key applications are:
| 2,2’-bis(diphenylphosphino)-1,1’-binaphthyl (BINAP) |
| (S)-Binol by resolution of the mother binol |
| (R)-Binol in the same resolution process |
| Aluminium Lithium bi(binaphthol) (its (R)-enantiomer) |
| (S)-Vanol |
A very recent but path-breaking application of Binol has been in preparation of one of the Covid-19 vaccines being developed and supplied from India.
