| 摘 要： | 1 INTRODUCTION 2-Aminochromene is an important class of com- pounds found as the main compounds of many natu- rally occurring products employed as cosmetics and pigments and utilized as potential biodegradeable agro- chemicals1～3]. In recent years, montmorillonite in natural and ex- changed forms has received considerable attention in different organic syntheses because of its environ- mental compatibility, low cost, high selectivity, reusa- bility and operational simplicity4], such as …

| Abstract: | The title compound 2-amino-5,6-dihydro-4-(3,4-dimethoxyphenyl)-4H-benzoh]-chromene-3-carbonitrile (C22H20N2O3, Mr = 360.40) was obtained by the reaction of 2-(3,4-dimeth-oxybenzylidene)-1-tetralone and malononitrile in DMF in the presence of KF-montmorillonite. Its structure was confirmed by IR and 1H NMR spectra. The crystal is of monoclinic, space group C2/cwith a = 24.101(6), b = 9.146(2), c = 17.238(3) (A),β= 95.92(2)°, Z = 8, V= 3779.4(14) (A)3, Dc =1.267 g/cm3, μ(MoKα) = 0.085 mm-1, F(000) = 1520, R = 0.0409 and Wr = 0.0981 for 2043observed reflections (1 ＞ 2σ(Ⅰ)). |
