Triflamides for protection and cyclization of tetraamines to tetraazamacrocycles
摘要:
A facile two-step synthesis of tetraazamacrocycles is reported starting from trifluoromethanesulfonyl derivatives of linear tetraamines. After cyclization, the macrocycle was deprotected using sodium in liquid ammonia.
