Highly selective TFAA-cleavage of tertiary 2,4-dimethoxybenzylamines and its use in the synthesis of secondary amines

Nussbaumer,Baumann,Dechat,Harasek

, p. 4591 - 4602 (1991)

TFAA-treatment of allylic, propargylic, homopropargylic and some benzylic tert. 2, 4-dimethoxybenzylamines leads to highly selective cleavage of their dimethoxybenzylic C-N bonds. The resultant trifluoroacetamides can then readily be converted to the corresponding secondary amines.
