Microwave Irradiation Promoted Reactions of Benzoxazin-4-Ones with Primary Amines. Preparation of 4(2=3H)-Quinazolinones
An efficient synthesis of 3-substituted or 2,3-disubstituted 4(3H)-quinazolinones from benzoxazin-4-ones and primary amines under microwave irradiation in unsealed vessels is described.
متن کاملpreparation of 3, 4-dihydropyrimidin-2(1H)-ones using quaternary ammonium- treated clay in water
In this study, a variety of 3, 4-dihydropyrimidin-2(1H)-ones derivatives were synthesized via three-component Biginelli reaction. The quaternary ammonium- treated clay -catalyzed process proved to be simple, efficient, and environmentally friendly.
متن کاملA Simple Method for the Preparation of Cis-(3-Azido-4-Styryl)-2-Azetidinone
The synthesis of the title compound is described. Deprotection of Cis(N-Trityl-3-azido-4-Styryl)-2-azetidinone to Cis-(3-azido-4-styryl)-2-azetidinone was found to be accelerated by the special salt effect under acidic condition
متن کاملPreparation of 4-Alkoxy-1-hydroxypyridine-2-thiones
Reactions of 2-chloro-4-fluoropyridine (8), 2-chloro-4-nitropyridine (9), and their corresponding N-oxides 7 and 3 with the n-heptanolate anion were investigated in three solvents. The desired 2-chloro-4-heptyloxypyridine-N-oxide (4a) was obtained most efficiently from 3 in DMSO. A reaction of 4a with AcSNa followed by deacetylation with MeONa gave the sodium salt of 4-heptyloxy-1-hydroxypyridi...
