A New Strategy for the Synthesis of Bis(alkadiynyl)amines and Azacycloalkadiynes Using Copper-Containing Catalysts
摘要:
An efficient method for the preparation of N-alkyl-N,N-di(alkadiynyl)amines and 1-alkyl-1-azacycloalkadiynes is developed via the aminomethylation reaction of ,-diacetylenes with N-alkyl-N,N-bis(ethoxymethyl)amines in the presence of copper halides as the catalysts.

N, N-Bis(ethoxymethyl) alkylamines function as effective reagents in the double-Mannich annulation of cyclic ketone substrates, providing efficient access to a series of azabicyclic ketones. These ring systems are a useful scaffold for the four-step synthesis of novel constrained homocholine analogues.
