  Syntheses of all poasible calix[6]arene derivatives with MeO- and ROCOCH2O- substituents and their metal binding properties

  摘要：

  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.

  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.

  p-tert-butylcalix[6]arene can be converted to transannularly bridged esters by treatment with diacid chlorides ranging from succinoyl to suberoyl and including terephthaloyl. The parent compounds p-tert-butylcalx[6]arene and p-H-calix[6]arene can also be transannularly bridged by treatment with bis-halomethylaryl compounds by using KOSiMe 3 as the base. Methylation of the resulting calix[6]arenes containing
