[Summary of the lecture] In this lecture, chemistry of heterocyclic compounds, especially natural alkaloids, is overviewed, and cyclization reactions and property of the heterocyclic compounds are explained. Also aromaticity and the related functionality are discussed.
Advanced Organic Synthesis II is subsequently opened after this course.
[Aim of the lecture] Heterocyclic structures are included in many drugs, agricultural chemicals, and electro-functional materials. In this lecture, heterocyclic chemistry that is prerequisite to researchers based on organic chemistry will be overviewed. Students will understand the fundamentals of synthesis and properties of heterocyclic compounds.
By the end of this course, students acquire the following ability:
(1) Overview chemistry of heterocyclic compounds.
(2) Explain properties of the heterocyclic compounds in nature.
(3) Explain methods of construction, fundamental properties, and functionality of heterocyclic compounds.
heterocycles, alkaloids, cyclizations, aldol reactions, catalytic reactions, cycloadditions, electron-deficient, electron-excessive, aromaticity
|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
This lecture will proceed in the following order: (1) overview of heterocyclic compounds, (2) synthetic methods for the cyclic structures, and (3) structure and properties of heterocycles. In the last day, practice problems and interpretation of them will be carried out to confirm the level of understanding.

Practice problems and interpretation for confirming the level of understanding (70%), level of class participation (30%) (The level of class
participation will be calculated by discussion, small examination and so on in the lecture.)
The condition of the study will not be made, but enrollment in the related course of organic chemistry is desirable.
