摘要

Efficient schemes for selective N-protection of 1,4,7-triazacyclononane and I ,5,9-triazacyclododecane and for synthesis of related bis-coronands are based upon the synthetic intermediacy of tricyclic orthoamides. ... Interest in azacoronands (medium and macrocyclic poly- amines) bearing pendant arms is currently high, because of the possibilities these systems offer for systematic variation of the type of ligand donor group and geometry of metal-ion complexation. Consequently, ...
