  New crown ether-like macrocycles containing a nitrophenol unit. Synthesis and metal ion effects on the reactivity of their acetates in transacylation reactions

  摘要：

  A series of crown ether-like macrocyclic compounds 3 containing the 2,6-dibenzyl-4-nitrophenol substructure have been prepared by cyclization reactions of disalicylideneacetone 4 with ditosylates 7 of oligoethylene glycols, followed by hydrogenation and double aldol condensation with nitromalondialdehyde. These compounds may be regarded as possessing a section of a 1,3-crowned calix[4]arene. X-ray analysis of two examples shows, however, that the three phenolic units linked via o-methylene groups adopt a conformation different to the all-cis conformation found in calix[4]arenes. The reaction of the nitrophenyl acetates derived from 3 and from suitable model compounds with ethoxide in ethanol was studied kinetically. This reaction is accelerated by the addition of SrBr2 and BaBr2 in all cases, indicating that the metal ion is bound more strongly to the transition state than to the initial state. Especially high acceleration factors (up to 700 in the case of 10e) were observed for cyclic and open-chain compounds with longer flexible oligoethylene oxide chains, which means that only in these cases do the ether oxygens contribute effectively to the binding of the metal ion in the transition state.

  °C to give the corresponding saturated carbonyl compounds; here hydrogenation of the CC bond was preferred over the CO bond. Under the same reaction conditions but using an excess of benzylamine, a tandem process is then favoured, starting also with the reduction of the CC bond followed by a nucleophilic addition of the primary amine to yield valuable saturated imines with good to excellent yields (62%–91%)

  已开发出一种基于镍膦配合物的简单均相催化体系，用于转移氢化和缩合α，β-不饱和酮，并使用伯胺作为氢供体，生成饱和的亚胺和饱和的亚胺。因此，在[（dippe）Ni（μ-H）] 2（dippe = 1， 2-双-（二异丙基膦基）-乙烷）在180℃下使用乙醇作为溶剂，得到相应的饱和羰基化合物；在此，C C键的氢化优于C O键。在相同的反应条件下，但使用过量的苄胺，则有利于串联反应，并且从还原C开始C键，然后亲核加成伯胺，可制得有价值的饱和亚胺，收率良好至优异（62％–91％）。
