Efficient Synthesis of N-Methylamides and Amines via 4-(Alkylamino)benzyl-N-methylamine as a New Protecting Group
摘要:
4-(Alkylamino)benzyl-N-methylamine is a good protecting group for the synthesis of N-methylamides and amines. The N-debenzylation of N-methylamides and amines can be carried out selectively and efficiently under condition using trifluoroacetic acid (TFA).
