  基于多酚的分子平台的定制功能化

  摘要：

  选择性修饰大环低聚物的通用且有效的方法很少见，主要是因为难以将反应限制在一定数量的相同官能团上。这项工作描述了由多酚平台iteroselective官能一个独特的，一般情况下，合理的方法ñ -叔-butylaminocarbonyl（BAC）组。该方法包括使低聚平台与t反应-BuNCO和非极性溶剂中的无机碱。此非常简单的一步步骤已应用于各种杯[4、5、6和8]芳烃，并且在所有情况下，均以高收率（> 90％）分离了具有单个剩余酚部分的杯芳烃。有趣的是，这种所谓的“一劳永逸”的方法可以直接访问具有固有手性的杯芳烃。还显示了Bac基团可以用作保护基团。因此，仅用一种方法已用于关键前体平台的有效单功能化，说明了其用于复杂大环低聚物定制合成的巨大潜力。

  Syntheses of All Possible O-Methylation Products Derivable from 5,11,17,23,29,35-Hexa-tert-butylcalix[6]arene-37,38,39,40,41,42-hexol

  摘要：

  We here report methods for the synthesis of all twelve possible 0-methylation products from 5,11,17,23,29,35-hexa-tert-butylcalix[6]arene-37,38,39,40,41,42-hexol (1): one mono-, three di-, three tri-, three tetra-, one penta-, and one hexamethylated products. The strategies used are (i) direct O-methylation with different 1/K2CO3 ratios, (ii) selective mono-O-methylation of O-alkylation products, (iii) demethylation with TiCl4 or LiI, and (iv) protection-deprotection with a benzyl group or an o- or m-xylenyl group. We believe that these O-methylation products are useful as basic skeletons to design functionalized calix[6]arenes with the desired number of substituents and regioselectively-positioned functional groups.

• Synthesis and NMR Spectroscopic Studies of Bridged and Capped Calix[6]arenes: High-Yield Syntheses of Unimolecular Caged Compounds from Calix[6]arene

  Calix[6]arenes were bridged with a xylenyl unit or capped with a mesitylenyl unit, and their conformational properties were examined by spectroscopic methods. As previously reported by Gutsche et al., the calix[6]arene bridged on 1,4-phenyl units could enjoy slow ring inversion. The calix[6]arene bridged on 1,a-phenyl units also showed the ring inversion behavior, whereas in the calix[6]arene bridged on 1,3-phenyl units, ring inversion was virtually suppressed because of destabilization of the transition state. The capping of 1,3,5-tri-O-alkylated calix[6]arenes with 1,3,5-tris(bromomethyl)benzene gave the products in high yields (80-91%). This advantage was accounted for by the C-3 symmetrical complementarity of these two reactants. In these capped products, ring inversion was inhibited under the present measurement conditions, and the presence of a unimolecularly closed inner cavity was suggested on the basis of H-1 NMR spectroscopy and MM3 calculations.

• Syntheses of all poasible calix[6]arene derivatives with MeO- and ROCOCH2O- substituents and their metal binding properties
  作者：Hideyuki Otsuka、Koji Araki、Seiji Shinkai

  日期：1995.8

  It has become possible to synthesize all possible calix[6]arene derivatives with MeO- and ROCOCH(2)O- substituents from corresponding O-methylated calix[6]arenes(2-7). The yields of these reactions were relatively high and the products could be easily purified because of the absence of other regioisomers. They are one mono-, three di-, three tri-, three tetra-, one penta-, and one hexa-EtOCOCH(2)O-substituted products. It was proved that O-methylation products act as useful basic skeletons to design functionalized calix[6]arenes with the desired number of ROCOCH(2)O substituents and the regioselectively-positioned ROCOCH(2)O groups.
