以杯[6]芳烃和杯[6]-1,4-冠-4为起始原料,经过醚化引入酯基,接着用水合肼肼解得到杯[6]酰肼衍生物2和6,然后再与水杨醛进行缩合反应,高产率合成了两例杯[6]酰腙衍生物3和7.化合物6与2倍的二水杨醛乙二醚进行“1+2”缩合反应,得到了一例新型结构的杯[6]-1,4-2,6-3,5-三桥联酰腙衍生物8,产率73%.新化合物2,3,6,7和8的结构经元素分析、红外光谱、质谱、核磁共振谱等证实.
Using calix [6] arene and calix [6] -1,4-crown-4 as starting materials, the ester groups were introduced through etherification and hydrazinolysis with hydrazine hydrate to obtain calix [6] hydrazide derivatives 2 and 6, And then with salicylaldehyde condensation reaction, high yield synthesis of two cup [6] acylhydrazone derivatives 3 and 7. Compound 6 and 2 times salicylaldehyde ethers for “1 +2 ” condensation reaction, A new type of calix [6] -1,4-2,6-3,5-tricyclohydrazone derivative 8 was obtained with a yield of 73%. The structures of the new compounds 2,3,6,7 and 8 The elemental analysis, infrared spectroscopy, mass spectrometry, nuclear magnetic resonance spectroscopy confirmed.
