Thiophene is a five-membered heterocyclic compound containing a sulfur heteroatom with the molecular formula C4H4S. Thiophene is aromatic and is very similar to benzene; electrophilic substitution reaction is easier than benzene, and it is mainly substituted at the 2-position. Thiophene ring system has certain stability to oxidant.
Imidazolidine is a heterocyclic compound (CH2)2(NH)2CH2. The parental imidazolidines are less studied, but related compounds substituted on one or both nitrogen centers are more common. Generally, they are colorless, polar, basic compounds. Imidazolidines are examples of cyclic 5-membered general amines. Imidazolidine derivatives are key components in the development of bioactive compounds for the treatment of various diseases, especially Chagas disease. In fact, other studies have shown that imidazoline-2,4-diones have a wide range of pharmacological activities, including anticonvulsant, antiarrhythmic, and antiparasitic.
