Using cheap, readily available, and economic active MnO2 as an oxidant, a series of 2,4-disubstituted quinazoline-3-oxides were synthesized in good to excellent yields by oxidation of the corresponding 1,2-dihydroquinazoline-3-oxides under mild

2-Aminobenzaldehyde, 1-(2-aminophenyl)ethanone, and 2-aminophenyl phenyl methanone oximes 1 were reacted with aromatic aldehydes to give the corresponding 1,2-dihydroquinazoline-3-oxides 2. The latter were converted in high yields to a series of quinazoli
Visible light-mediated synthesis of quinazolines from 1,2- dihydroquinazoline 3-oxides
Chen, Yi-Chou,Yang, Ding-Yah
, p. 10438 - 10444 (2013/11/19)
A series of quinazolines were synthesized in good to excellent yields by exposing 1,2-dihydroquinazoline 3-oxides to visible light in acetonitrile without the presence of any external sensitizers. The only exception was the 2-(p-nitrophenyl)-substituted s
