Abstract
Disclosed is a process for producing a protected optically active fluoroamine, which comprises the step of reacting an imine-protected optically active hydroxyamine, an oxazolidine-protected optically active hydroxyamine, or a mixture of the imine-protected optically active hydroxyamine and the oxazolidine-protected optically active hydroxyamine, with sulfuryl fluoride (SOF) in the presence of a tertiary amine having a carbon number of 7 to 18 (produced by substituting all of three hydrogen atoms in ammonia by alkyl groups). The desired optically active fluoroamine can be produced by hydrolyzing the protected optically active fluoroamine under acidic conditions.
