TiO2/nanoclinoptilolite, a recyclable and high efficient heterogeneous nanocatalyst, for the synthesis of 2-amino-4H-chromene derivatives
The synthesis of pharmaceutically and biologically active 2-amino-4H-chromenes was described using TiO2/nanoclinoptilolite (TiO2/NCP) as an efficient nanocatalyst under solvent-free condition. The TiO2/NCP was fabricated through modification of NCP with HDTMA, then the surface modified NCP was impregnated with titanium tetrachloride solution. Finally, the materi...

متن کامل2-Amino-7,7-dimethyl-5-oxo-4-[3-(trifluoromethyl)phenyl]-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile
In the title mol-ecule, C19H17F3N2O2, the fused cyclo-hexene and pyran rings adopt sofa and flattened boat conformations, respectively. The four essentially planar atoms of the pyran ring [maximum deviation = 0.008 (2) Å] form a dihedral angle of 88.13 (9)° with the benzene ring. The F atoms of the trifluoro-methyl group were refined as disordered over three sets of sites in a 0.507 (7):0.330 (...
متن کاملAluminum Oxide Nanoparticle as a Valuable Heterogeneous Nanocatalyst in the Synthesis of 2-Aminothiazole Scaffolds
An efficient methodology for the preparation of 2-aminothiazoles is achieved by one-pot reaction of methylcarbonyls, thiourea and iodine in the presence of an aluminum oxide nanoparticle as an active nanocatalyst at 85 °C in DMSO solvent. Al2O3 nanoparticles have been prepared via co-precipitation method and their structures were confirmed using Fourier transform infrared radiation (FT-TR), X-r...
متن کامل2-Amino-4-(2-chlorophenyl)-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile hemihydrate
The asymmetric unit of the title compound, C(18)H(17)ClN(2)O(2)·0.5H(2)O, contains two organic mol-ecules and one solvent water mol-ecule. In each organic mol-ecule, the cyclo-hexene ring adopts an envelope conformation with the C atom connecting the two methyl groups on the flap; the 4H-pyran ring is nearly planar [maximum deviation = 0.113 (3) Å in one mol-ecule and 0.089 (3) Å in the other m...
