英文摘要: A new series of multiply hydrogen-bonded heterodimers have been self-assembled in chloroform-d, with ureidopyrimidone derivatives 2 and 3 and 2,7-diamino-1,6-naphthyridine diamide 4 and ureas 5 and 6 as monomers. The self-associating behavior of the compounds and the binding modules of the new heterodimers have been investigated. New tri-center hydrogen bonds have been proposed to explain the stability of the new heterodimers. 2D-NOESY, COSY and temperature variable H-1 NMR studies revealed that all the new heterodimers are substantially more stable than the ureidopyrimidone-based quadruply hydrogen-bonded homodimers in chloroform-d. As a result, heterodimers 2.4 and 3.4 were assembled quantitatively, while heterodimers 2.5, 3.5, 2.6, and 3.6 were formed in 80-85% yields. It is also revealed that intramolecular hydrogen bonds formed in monomers 5 and 6 reduce the stability of the corresponding heterodimers. (C) 2004 Elsevier Ltd. All rights reserved.
