Process for production of amines
-
Page/Page column 48, (2008/06/13)
A process for producing an amine which is characterized by reacting an imine with a nucleophilic compound (except a trialkylsilyl vinyl ether) in the presence of a phosphoric acid derivative represented by the formula (1): wherein A1 represents a spacer; X1 and X2 represent 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 medicines, 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.

The replacement of non-bridging sulfur in five-membered cyclic phosphorothioates by oxygen nucleophiles in the presence of bromine occurs with retention of configuration and has allowed the 31P NMR signals of the diastereoisomeric tert-butyldiphenyl silyl esters of 2',3'-cyclic adenosine monophosphate to be assigned.
