Synthesis 15-membered Triolefinic Macrocycles and Modification the Poly(propyleneimine)

摘要:

以1,4-二溴-2-丁烯，4-氟苯磺酰胺,2,4,6-三异丙基磺酰胺为主要原料，采用五步法合成一种含氮的十五元三烯大环化合物-(E,E,E)-1,6-二[(2,4,6-三异丙基苯基)磺酰基]-11-[(4-氟苯基)磺酰基]-1,6,11-三氮环十五烷-3,8,13-三烯。进而使用十五元三烯大环化合物改性2.0代的聚丙烯亚胺树状聚合物（2.0G PPI，实验室自制）的表面基团，制备聚丙烯亚胺杂化树形聚合物。利用核磁共振和红外光谱表征了中间产物和目标产物的结构,结果表明：所得的中间产物和目标产物均符合分子设计要求，合成路线合理可行。

Abstract:

Synthesis a nitrogen-containing 15-membered triolefinic macrocycles by five-steps method[(E,E,E)-1,6–Bis[(2,4,6-triiso-propylphenyl)sufonyl]-11-[(4-fluorophenyl)sulfonyl]-1,6,11-triazacyclopentadeca-3,8,13-triene] with 1,4-dibromo-2-buten, 4-fluorobenzenesulfonam, 2,4,6-triisopropylbenzenesulfonamide as the main reactant. The surface group of the 2.0 generation poly(propyleneimine) dendrimer(2.0G PPI) , which is prepared by the co-worker of the laboratory, is modified by the 15-membered triolefinic macrocyclic compounds to synthesis hybrid poly(propyleneimine) dendrimer. The products were proved to be in accord with the theoretical structure by characterization with infrared and nuclear magnetic resonance spectroscopy.
