Topic

Heterocyclic chemistry is an important subdivision of organic chemistry, as 70% of all medicines are heterocyclic compound or contains a heterocyclic moiety. This course will give an introduction to, and the summary of, the most important principles and ideas of heterocyclic chemistry. This course partially re-calls the knowledge of Organic chemisty 1 and Organic chemistry 2 course, discusses those details which were not reflected on, because of time shortage and supports to evaluate the pharmacological chemistry subject.

-Electronic structure of heterocycles

-Nomenclature of heterocyclic compounds

-Main synthetic routes to heterocyclic compounds, Saturated heterocycles, occurence of heterocycles

-Three and four membered heterocycles (synthesis, reactions, occurence)

-The pyrrole and indole (synthesis, reactions, occurence)

-Furan, thiophene and their benzo derivatives.

-Five membered heterocycles with two or more heteroatoms: imidazole, oxazole, thiazole

-Pyrazole, isoxazole, isothiazole

-I. st test, Six-membered heterocycles with one oxygen heteroatom (piranes, chromones, flavones and coumarins)

-Six membered heterocycles with one nitrogen atom (pyridine, quinoline, isoquinoline)

-Six membered heterocycles with two or more heteroatoms (purine, diazines, triazines etc.)

-Seven membered heterocyclic chemistry

-Heterocycles in supramolecular chemitry

-Heterocyclic compounds in organic snthesis

-II nd test, short presntation on a paper on heterocyclic chemistry

-Evaluation

Conditions for acceptance of the semester

-

Mid-term exams

The students write two tests, at the middle of the semester and at the end of the semester. Every student have a chance to make a presentation based on a heterocyclic chemistry paper for an extra grade.

Making up for missed classes

Personal communication. The english program student might visit the paralell hungarian course to catch up the main reaction equations.
