Zr(HSO4)4: An Efficient Catalyst for the Synthesis of 3-(2'- Benzothiazolyl)-2, 3-dihydroquinazolin- 4(1H)-ones. Issue 2 (2012) - Wu, Liqiang
Abstract : A simple and efficient synthesis of 3-(2'-benzothiazolyl)-2, 3-dihydro quinazolin-4(1 H )- ones has been accomplished by the one-pot condensation of isatoic anhydride, aldehyde and 2-aminobenzothiazole under solvent-free conditions in the presence of Zr(HSO4 )4 .
