DOI: 10.1007/s13738-017-1109-x
Abstract: An efficient, inexpensive and recyclable sulfated polyborate catalyst was applied in a three-component, one-pot cyclocondensation of isatoic anhydride, aldehydes and ammonium acetate/amines to afford the corresponding 2,3-dihydroquinazolin-4(1H)-ones. The key advantages of the present method are… read more here.

DOI: 10.1016/j.ejmech.2018.06.005
Abstract: Using a classical hybridization approach, a series of 1H-benzo[d]imidazoles and 3,4-dihydroquinazolin-4-ones were synthesized (39 examples) and evaluated as inhibitors of Mycobacterium tuberculosis growth. Chemical modification studies yielded potent antitubercular agents with minimum inhibitory concentration (MIC)… read more here.
