Distinguished Professor Sukbok Chang Named the 2022 Ho-Am Laureate
Distinguished Professor Sukbok Chang from the Department of Chemistry was named the awardee of the Ho-Am Prize in the fields of chemistry and life sciences. The award has recognized the most distinguished scholars, individuals, and organizations in physics and mathematics, chemistry and life sciences, engineering, medicine, arts, and community service in honor of the late founder of Samsung Group Byong-Chul Lee, whose penname is Ho-Am. The awards ceremony will be held on May 31 and awardees will receive 300 million KRW in prize money.
Professor Chang became the fourth KAIST Ho-Am laureate following Distinguished Professor Sang Yup Lee in engineering in 2014, Distinguished Professor Jun Ho Oh in engineering in 2016, and Distinguished Professor Gou Young Koh in medicine in 2018.
Professor Chang is a renowned chemist who has made pioneering research in the area of transition metal catalysis for organic transformations. Professor Chang is also one of the Highly Cited Researchers who rank in the top 1% of citations by field and publication year in the Web of Science citation index. He has made the list seven years in a row from 2016.
Professor Chang has developed a range of new and impactful C-H bond functionalization reactions. By using his approaches, value-added molecules can be readily produced from chemical feedstocks, representatively hydrocarbons and (hetero)arenes. His research team elucidated fundamental key mechanistic aspects in the course of the essential C-H bond activation process of unreactive starting materials. He was able to utilize the obtained mechanistic understanding for the subsequent catalyst design to develop more efficient and highly (stereo)selective catalytic reactions.
Among the numerous contributions he made, the design of new mechanistic approaches toward metal nitrenoid transfers are of especially high impact to the chemical community. Indeed, a series of important transition metal catalyst systems were developed by Professor Chang to enable the direct and selective C-H amidation of unreactive organic compounds, thereby producing aminated compounds that have important applicability in synthetic, medicinal, and materials science. He has also pioneered in the area of asymmetric C-H amination chemistry by creatively devising various types of chiral transition metal catalyst systems, and his team proved for the first time that chiral lactam compounds can be obtained at an excellent level of stereoselectivity.
Another significant contribution of Professor. Chang was the introduction of dioxazolones as a robust but highly reactive source of acyl nitrenoids for the catalytic C-H amidation reactions, and this reagent is now broadly utilized in synthetic chemistry worldwide.
Professor Chang also leads a research group in the Center for Catalytic Hydrocarbon Functionalizations at the Institute for Basic Science.

Professor Suk-Bok Chang receives 14th Korea Science Award in the field of Chemistry
Professor Suk-Bok Chang from the Department of Chemistry at KAIST received the “2013 Korea Science Award” in chemistry hosted by the National Research Foundation and the Ministry of Science, ICT, and Future Planning, Republic of Korea.
The Korea Science Award is a presidential award of Korea, which was first established in 1987 to recognize research excellence in natural science. Three scientists are selected for the award in every other year.
Professor Chang primarily researches the catalyzing mechanism of carbon-hydrogen bonds in organic molecules. He has succeeded in making great progress in the field of organic chemistry especially in developing a new type of transition metal catalytic behavior that can be applied to low-reactivity compounds.
Hydrocarbons are abundant in nature, but its unreactive nature in ambient conditions makes it unsuitable as reactant for compound synthesis. In addition, the mechanism behind transition metal catalyzed carbon-hydrogen bond synthesis has not been proven sufficiently.
The prediction that fossil fuels will be depleted before the end of the century makes hydrocarbon synthesis an extremely important matter.
The need for an effective hydrocarbon synthesis method inspired Professor Chang to pursue research in the transition metal catalysis method and to develop a catalytic system that would allow efficient synthesis even in ambient conditions.
Professor Chang has been the lead researcher for the Institute for Basic Science’s “molecule catalysis reaction research team” since December 2012 and has been carrying out this research in KAIST.
