Benzocycloheptenes are cycloheptenes with additional benzene rings attached. Most have two benzene rings, and are called dibenzocycloheptenes. Some benzocycloheptenes and substituted benzocycloheptenes have medical uses as antihistamines, anticholinergics, antidepressants, and antiserotonergics. Examples include: Antihistamines and ...
Dibenzocycloheptene (also known as dibenzosuberane and dibenzocycloheptadiene) is a tricyclic chemical compound featuring two benzene rings bound to a cycloheptene group. It is an occasional motif in synthetic organic chemistry. [ 1 ]
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). [1] Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles .
Many simple aromatic rings have trivial names. They are usually found as substructures of more complex molecules ("substituted aromatics"). Typical simple aromatic compounds are benzene, indole, and pyridine. [1] [2] Simple aromatic rings can be heterocyclic if they contain non-carbon ring atoms, for example, oxygen, nitrogen, or sulfur.
James Tour's research group designed and synthesized these compounds in 2003 as a part of a sequence on chemical education for young students. [2] The compounds consist of two benzene rings connected via a few carbon atoms as the body, four acetylene units each carrying an alkyl group at their ends which represents the hands and legs, and a 1,3 ...
Benzothiazine is a heterocyclic compound consisting of a benzene ring attached to the 6-membered heterocycle thiazine. The name is applied to both the 2H- and 4H-isomers of the molecule. 2,1-Benzothiazine, a type of benzothiazines was first reported in the 1960s. Subsequently, their preparation and intensive biological and physiological studies ...
This group typically excludes compounds in which either benzene is fused to another ring (bicyclic, tricyclic, polycyclic) [1] or includes a heteroatom, or where the methane connects to three or four benzenes. Ball-and-stick model of the benzhydryl radical. The benzhydryl radical can be abbreviated Ph 2 CH• or Bzh. [2]
Benzopyran is a polycyclic organic compound that results from the fusion of a benzene ring to a heterocyclic pyran ring.. According to current IUPAC nomenclature, the name chromene used in previous recommendations is retained; however, systematic ‘benzo’ names, for example 2H-1-benzopyran, are preferred IUPAC names for chromene, isochromene, chromane, isochromane, and their chalcogen ...
