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).

N,N‐Dimethylanilin (4) und N‐Methylen‐morpholiniumchlorid (10g) reagieren über 4‐Morpholinomethyl‐N,N‐dimethylanilin (9g) zu 2,4‐Bis(morpholinomethyl)‐N,N‐dimethylanilin (11g). Aus 4‐Dimethylaminomethyl‐ oder 4‐Pyrrolidinomethyl‐N,N‐dimethylanilin (9a bzw. 9e) und allen eingesetzten Dialkylmethyleniminiumchloriden 10 entstehen hingegen keine zweifach im Kern aminomethylierten Produkte 11 sondern die
