‘Reversed’ regioselectivity in the reduction of epoxides with lithium 9,9-di-n-butyl-9-borabicyclo[3.3.1]nonanate
Abstract
Lithium 9,9-di-n-butyl-9-borabicyclo[3.3.1]nonate reduces aromatic epoxides at the most sterically hindered position, while aliphatic epoxides are reduced at the least hindered position.
