In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Microwave-assisted synthesis of quinazolinone derivatives by efficient and rapid iron-catalyzed cyclization in water, published in 2009-11-30, which mentions a compound: 20198-19-0, Name is 2-Aminoquinazolin-4(3H)-one, Molecular C8H7N3O, Name: 2-Aminoquinazolin-4(3H)-one.
A green, rapid, and efficient method was developed for synthesizing quinazolinone derivatives, e.g., I from substituted 2-halobenzoic acids and amidines via microwave-assisted iron-catalyzed cyclization with or without ligand in water or DMF. With these methods, moderate to high yields of the desired products can be obtained from even inactive substrates, such as guanidines. This is the first report on the synthesis of N-heterocyclic compounds by iron-catalyzed C-N coupling in aqueous media.
After consulting a lot of data, we found that this compound(20198-19-0)Name: 2-Aminoquinazolin-4(3H)-one can be used in many types of reactions. And in most cases, this compound has more advantages.
