Synthesis of Some 6-Bromo-3-- and 2-Styryl-3--4(3H)-quinazolinones

Varma, Rajendra S.,Bahadur, Surendra,Agnihotri, Anil K.

, p. 103 - 104 (2007/10/02)

Some substituted 6-bromo-3--4(3H)-quinazolinones have been synthesized under the conditions of the Mannich reaction.In addition, a few unsubstituted and substituted 2-styryl-4(3H)-quinazolinones, 6-bromo-2-styryl-4(3H)-quinazolinones, and 6-bromo-2-styryl-3--4(3H)-quinazolinones have also been synthesized by condensing the corresponding 2-methyl derivative with an appropriate aromatic aldehyde.Representative compounds have been screened for their central neural system and antiviral activity.
