새로운 이민기를 포함하는 비스 크라운에테르의 합성(IV)
Syntheses New Bis-Crown Ethers Containing Imine Group(IV)
We report herein synthetic results obtained six new types of bis-benzocrown ethers containing imine group. Bis crown ethers 1 ~ 3 are aminobenzo-15-crown-5-ether linked with terephthalaldehyde, isophthalaldehyde, phthaldehyder espectively by imine reaction. Bis crown ethers 1 ~ 3 are different distances in each crown ether rings. Bis crown ether 4 has large cavity in crown ethers. The synthesized crown ethers were characterized respectively by IR, NMR. GC-Mass.
