The objects of bioscience and biotechnology are apparently organic compounds. Thus, this lecture systematically and comprehensively describes fundamental topics necessary for the use of or the research on organic compounds, including the knowledge and theory on their nomenclature, nature, analysis, reactions, synthesis, and utility. The contents consist of the IUPAC nomenclature, the electronic states and bonding of molecules, three-dimensional structures of molecules, the instrumental analysis of molecular structures (NMR, IR, Ms), reactions of each functional group, the carbon-carbon bond formation and organic synthesis, and utility of natural and artificial organic compounds, which will be lectured according to the textbook, with the theoretical background and relationship between the topics being mentioned.
At the outset, this course allows the student to firmly learn the general knowledge and theory common to individual topics, such as the nomenclature of compounds, electronic states and bonding of molecules and their nature and structures owing to the former, and the electronic theory of organic chemistry essential to the description of reaction mechanisms. At the next stage, the students will proceed to study reactions unique to each functional group and the instrumental analysis of molecular structures, which are not only memorized but also well interpreted by them on the basis of the above general notion. While reviewing the previous two steps, the students are requested to increase their ability to understand the application of the fundamental topics, for example, the synthesis of organic compounds and utility of natural and artificial compounds. As a whole, this lecture will provide students basic knowledge and theory of organic chemistry and, at the same time, its covering area of utility of organic compounds.
By the end of this course, students will be able to:
1. Understand the chemistry of enols, enolates, and aldol condensation.
2. Understand the property and reaction of carboxylic acids and their derivatives.
3. Understand the property and reaction of amines and their derivatives.
4. Understand the reactivity of benzene substituents.
5. Understand the chemistry of ester enolates and Claisen condensation.

|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||Practical and/or problem-solving skills|
The lecture is to be done in order according to the textbook. (Thus, students are encouraged to familiarize the expected pages of the textbook in advance to the class and to review them after the class.) Students are given concise exercise problems for the last 10 minutes of each class, and their solutions and remarks will be explained at the beginning of the next class.

Students will be assessed on the concise exercise problems in each class (30%) and the final exam (70%).
As there is no duplication of the contents from Organic Chemistry I (alkanes and haloalkanes) to IV (carbonyl compounds and amines), the systematic study in this order will maximize its efficiency. Therefore, students are advised to enroll all of them in serial order. After completion of these courses, more advanced lectures, Bioorganic Chemistry and Pharmaceutical Chemistry, are available. Thus, students can proceed to the higher level of organic chemistry by taking one or both of them, dependent on their interest.
