Selective Mono- and 1,4-Di-N-alkylations of 1,4,7,10-Tetraazacyclododecane.
摘要:
General methods for selective N-alkylations of the macrocycle 1,4,7,10-tetraazacyclododecane have been developed. The N-monoalkylation proceeds via a cyclic guanidinium derivative, and the regioselective 1,4-N,N-dialkylation via a cyclic amidinium derivative. All transformations were high yield reactions.
