  ‘Double chiral’ new members of calixsalen family

  摘要：

  Synthesis and X-ray diffraction studies on the first examples of 'double chiral' calixsalens are presented. In these molecules, one can clearly distinguish two chiral zones. The first one is made by the macrocycle base, whereas the second chiral zone is set up of the additional chirality elements in the tail of the molecule. The 'double chiral' calixsalens are formed through cyclocondensation between chiral vicinal diamine of trans-1,2-diaminocyclohexane type and chiral C-5 substituted 2-hydroxyisophthalaldehyde derivatives. The absolute configuration of the dialdehyde did not affect the yield of the macrocyclization reaction. The presence of secondary amides in the tail part of the macrocycle leads to formation of hydrogen bonding network in the solid state, while sterical hindrance preserve interdigitation, thus, 'double chiral' calixsalens do not form aggregates typical for other calixsalens.

  Asymmetric synthesis of new atropisomerically multilayered chiral targets has been achieved by taking advantage of the strategy of center-to-multilayer chirality and double Suzuki–Miyaura couplings. Diastereomers were readily separated via flash column chromatography and well characterized. Absolute configuration assignment was determined by X-ray structural analysis. Five enantiomerically pure isomers

  通过利用中心到多层手性和双 Suzuki-Miyaura 耦合的策略，已经实现了新的阻转异构多层手性目标的不对称合成。非对映异构体很容易通过快速柱色谱分离并很好地表征。绝对配置分配由 X 射线结构分析确定。五种具有多层手性的纯对映异构体是利用涉及富电子芳香连接的锚来组装的。从市售起始材料经过 11 个步骤，最终获得 0.69% 的带有羟基连接的目标物的总产率。
