An intramolecular aryne Diels–Alder reaction with a furan moiety was applied to the synthesis of dihydrobenzo[de]isochromenes as intermediates toward naphthalimides. After oxidation, this method offers an efficient approach for the synthesis of substituted naphthalimides, which showed potent cytotoxic activity against HT-29 human cancer cell line.
具有呋喃部分的分子内芳烃Diels-Alder反应用于合成二氢苯并[ de ]异色酮,作为向萘二甲酰亚胺的中间体。氧化后,该方法为合成取代的萘二甲酰亚胺提供了一种有效的方法,该替代的萘二甲酰亚胺显示出对HT-29人癌细胞系的有效细胞毒活性。

In relation to the syntheses of exo- and endo-calixnaphthalenes, the chemical reactions of several 2- and 3-hydroxymethylnaphthols, as well as other substituted naphthols, with formaldehyde under a variety of condensation reaction conditions were evaluated. In several instances, o-naphthoquinomethides were the putative intermediates which were formed and which resulted in hetero-Diels–Alder [4+2]cyclodimerization

3a are reported. A convergent synthesis of the linear hexahomotrimer precursors 19 and 19a is described, but the direct synthesis of 3 and 3a can also be achieved from the monomers 20 and 20a, respectively. A limited study of the bindingproperties of alkali-metal cations by 3 or 3a using a picrate-CHCl3 extraction showed only weak abilities to bind with the cations examined.
