    Calixarenes. 32. Reactions of calix[4]quinones
    摘要:
    Calix[4]quinones are readily accessible by direct oxidation of p-tert-butylcalix[4]arenes as mono-, di-, tri- or tetraquinones depending on the number of free phenolic rings in the calixarene. The mono- and diquinones are shown to be useful synthesis intermediates in the following processes: (a) 1,2-carbonyl additions with malononitrile in the presence of secondary amines to yield p-[1-(dialkylamino)-2,2-dicyanovinyl] calixarenes (11) or with malononitrile in the absence of amines to yield p-(1,2,2-tricyanovinyl)calixarenes (9); (b) 1,2-carbonyl addition with pyrrolidine to yield a p-pyrrolidinocalix[4]arene (14); (c) 1,4-conjugate additions with a variety of nucleophiles, including sodio diethyl malonate, acetate, thiourea, p-thiocresol, and mercaptoacetic acid to give the chiral calixarenes 16-2 1.

    摘要:
    通过在有机溶剂中用Tl(NO 3)3 ·3H 2 O氧化25,27-二烷氧基杯[4]芳烃2a-e,合成了几种在相对位置(对位)具有醌部分的杯[4]芳二醌3a-e。。这些化合物的构象性质已通过X射线晶体学确定为固态,而在溶液中通过可变温度动态NMR确定。我们发现,杯[4]芳烯二醌3a-e比母体25,27-二烷氧基杯[4]芳烃2a-e更柔软在溶液中,取决于烷氧基的空间体积,倾向于呈现两种不同的固态部分锥体结构。循环伏安法表明,杯[4]亚芳基醌3a-e的氧化还原性质取决于其构象性质。

    Several calix[4]arenediquinones 3a-e having quinone moieties in opposite positions (diametrical) have been synthesized by oxidation of 25,27-dialkoxycalix[4]arenes 2a-e with Tl(NO3)3 · 3H2O in organic solvents. The conformational properties of these compounds have been established in the solid state by X-ray crystallography and in solution by variable-temperature dynamic NMR. We found that the calix[4]arenediquinones
