报告人简介：

Sehoon Park was born in Seoul, Korea. He received his Ph.D. (2008)from Tokyo Institute of Technology under the co-supervision of Prof. KohtaroOsakada and Prof. Daisuke Takeuchi. He then worked as a postdoctoral fellowwith Prof. Maurice Brookhart at the University of North Carolina at Chapel Hill(2009–2012). From 2013 to 2019, he was at the Institute for Basic Science(Korea) with Prof. Sukbok Chang, where he was promoted to tenure-track researchfellow (2017) and also served as an adjunct professor at the Korea Universityof Science and Technology since 2016. In early 2019, he joined GuangdongTechnion – Israel Institute of Technology (GTIIT) as an assistant professor,became an associate professor in 2022, and currently serves as the AcademicHead of EHS. His research focuses on synthetic and mechanistic organometallicchemistry, particularly dearomative hydroelementation of N-heteroarenes andrelated cascade transformations. 

报告摘要：

Inthe first part of this seminar, we present our recent developments intransition metal (Rh, Co)-catalyzed (asymmetric) double hydroboration ofquinolines and pyridines.1-3 Particular emphasis is placed on highlychallenging, unprecedented ligand-controlled regiodivergent double hydroboration of pyridines. As a catalytic platform, this methodology enablesthe selective synthesis of two pairs of multifunctionalized piperidine isomers.4The origin of this regiodivergent ligand effect is elucidated through combinedexperimental and computational mechanistic studies. The second part of thepresentation describes the extension of this substrate scope from pyridines toacyclic conjugated systems—including enals, enones, and enimines—by employingsustainable and straightforward Co-based catalytic systems.5This unifiedcatalytic approach establishes the first example of metal-catalyzed(regiodivergent) (asymmetric) double hydroelementation (E ≠ H) of pyridines, aswell as the first (asymmetric) double hydroelementation (E ≠ H) of enones andenimines.
