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.
