The synthesis of series of D2h and C2v symmetric oxygenated aromatic dicarboxaldehydes, using dilithiation methodology, is described along with their reactivity in the [3 + 3] cyclocondensation reaction with (1R,2R)-diaminocyclohexane to give oxygenated trianglimine macrocycles. Macrocycles derived from C2v symmetric dialdehydes give macrocycles with a stereogenic aromatic plane with complete diastereocontrol, as a mixture of rotamers.
本文介绍了利用二锂化方法合成一系列 D2h 和 C2v 对称含氧芳香族二甲醛的过程,以及它们与 (1R,2R)-二氨基环己烷发生 [3 + 3] 环缩合反应生成含氧三醯亚胺大环的反应活性。由 C2v 对称二醛衍生出的大环具有完全非对映控制的立体芳香面,是一种转子的混合物。
