Teaching Assistant: 임형근 (Hyeonggeun Lim, rahzell@kaist.ac.kr)

Course Prerequisites:

Organic Chemistry I (CH221), Organic Chemistry II (CH223), Bioorganic Chemistry (CH325), Physical Organic Chemistry (CH336, encouraged)

Course Description:

- Important topics in organic chemistry will be discussed in depth with a spectrum ranging from classical examples to the state of the art cases.

- This course discusses representative name reactions, their mechanism, and synthetic applications in organic chemistry.

- This course is designed to be complementary to other organic chemistry courses such as Organometallic Chemistry (CH542), Organic Synthesis I (CH522), and Organic Synthesis II (CH523). In other words, pericyclic reactions and carbonyl chemistry (1,2 and 1,4 addition, stereochemistry) won’t be discussed in details in this course.

- Details in drawing arrow-pushing mechanisms, heterocycles syntheses, detailed olefin synthesis methods, various olefin functionalizations, practical metal catalyzed cross-coupling reactions, metal catalyzed allylations, organolithium chemistry, Aggarwal chemistry, olefin metathesis, radical chemistry, strategies in complex molecules synthesis will be discussed.
