Title:
PROCESS FOR PRODUCTION OF AMINES
Document Type and Number:
WIPO Patent Application WO/2005/070875
Kind Code:
A1
Abstract:
A process for the production of amines which is characterized by reacting an imine with a nucleophilic compound (except trialkylsilyl vinyl ethers) in the presence of a phosphoric acid derivative represented by the general formula (1): (1) (wherein A1 is a spacer; X1 and X2 are each independently a divalent nonmetal atom or a divalent nonmetal atomic group; and Y1 is oxygen or sulfur). The invention provides a process by which amines (particularly optically active amines) useful as intermediates of drugs, agricultural chemicals, or the like can be produced without special post-treatment in high yield at high optical purity; and phosphoric acid derivatives (particularly optically active phosphoric acid derivatives) useful in the production of the amines.
