摘要:
A simple and efficient method for the synthesis of 9,9‐dimethyl‐9,10‐dihydro‐8H‐benzo‐[α]xanthen‐11(12)‐one derivatives (DDBXs) was developed by the condensation reaction of various substituted aryl aldehydes with 2‐naphthol and dimedone using Fe3O4 magnetic nanoparticles (MNPs) as a heterogeneous catalyst under solvent‐free conditions at 90–110 °C.The experimental procedure is very simple,the products are formed in high yields and the catalyst is easily separated by applying an external magnetic field.

摘要:
Cerium(IV) sulfate tetrahydrate, Ce(SO4)2·4H2O, is a novel inorganic solid acidic catalyst that efficiently catalyzes the synthesis of 2,3-dihydroquinazolin-4(1H)-ones via the one-pot three- component reaction of isatoic anhydride, aromatic aldehydes, and a nitrogen source(ammonium acetate, ammonium carbonate, ammonium chloride, or methylamine) under solvent-free conditions. The desired products are obtained in short reaction time with high yields. The catalyst is inexpensive and readily available and can be recovered conveniently and reused such that considerable catalytic activity can still be achieved after the fifth run. Easy work-up and avoiding the use of harmful organic solvents are other advantages of this simple procedure.

摘要:
The title compound was synthesized from 3-(2-methylphenyl)-2-thioxo-2,3-dihy- droquinazolin-4(1H)-one (4) which was prepared from 2-methylaniline in two steps. The structure was supported by the spectroscopic data and unambiguously confirmed by single-crystal X-ray diffraction studies. It crystallizes in the orthorhombic space group Pbca with unit cell dimensions a = 6.687(4), b = 24.788(16), c = 30.453(19) V = 5048(5) 3 and Z = 8.
