Kinetic Resolution of Unprotected BINOLs via Lewis Base-Catalyzed O-Boc Protection
{{output}}
A Lewis base-catalyzed kinetic resolution of 1,1'-bi-2,2'-naphthols (BINOLs) through atroposelective O-Boc protection is described. Using a commercially available biscinchona alkaloid catalyst, a broad range of unprotected BINOLs undergo selective transforma... ...
