7月27日（木）より講演会を開催します。

講師：Professor Ying Yeung YEUNG (The Chinese University of Hong Kong)

講演題目：Catalytic Asymmetric Halogenations and Their Synthetic Applications

日時：2023年7月27日（木）15時30分

場所：南7号館7階セミナー室

講演概要：Halogenation is an important class of organic transformation. Over the pass decades, reactions including cohalogenation, haloetherification, halolactonization and polyene cyclization are well documented. These reactions have been applied in the synthesis of many natural products and drug molecules. One of the research focuses in our research group is on the development of novel bromination reactions using N-bromosuccinimide (NBS), which is an easy handle and inexpensive halogen source. Recently, we have developed chiral chalcogen catalysts in various asymmetric halogenation reactions. Various useful building blocks such as bisphenols and spirolactones were prepared with good yields and ees. In this lecture, our recent progress in the development of organocatalytic and highly diastereoselective and enantioselective bromination reactions will be presented.

Yeung教授は，有機分子触媒を用いた不斉触媒反応の開発研究で顕著な業績をあげています。今回北海道大学の招へい研究員として来日されており，本学でも講演していただくことになりました。

多数の皆様のご参加をお待ちしています。
