With the support of the Chemical Synthesis (SYN) program in the Division of Chemistry, Professor Daniel Seidel of the Department of Chemistry at the University of Florida is studying new methods for asymmetric catalysis, particularly in the important area of chiral Brønsted acid catalysis. The ability to prepare complex chiral molecules in the most cost-effective way possible is directly dependent on the availability of sustainable synthetic methodologies. The new synthetic methods being explored and developed in this work have the potential to provide improved access to important compounds such as polycyclic ethers and lactams, with potential applications in the chemical and pharmaceutical industries, as well as throughout academia. Furthermore, this project provides an ideal training ground to prepare the next generation of researchers in the chemical sciences. Undergraduate students from different institutions will participate in the planned activities.This project aims to advance the field of asymmetric catalysis on a fundamental level through exploration of conceptually new and underdeveloped methods of substrate activation. A major goal is the development of reactions that produce enantiomerically enriched products through intervention of chiral ion pairs. Novel Brønsted acids and hydrogen bond donor catalysts will be explored to facilitate unprecedented enantioselective processes and address challenging synthetic problems. There is real room for innovation in this area as most such chiral Brønsted acid catalysts studied heretofore are based upon now familiar BINOL-phosphate frameworks. A focus is on reactions that proceed via the intermediacy of highly reactive oxocarbenium ions and related species. Multifunctional catalysts are being developed with the goal of achieveing enzyme-like catalysis and enantioselectivity under mild reaction conditions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在化学化学分校的化学合成计划的支持下，佛罗里达大学化学系教授丹尼尔·塞德尔（Daniel Seidel）正在研究不对称催化的新方法，尤其是在手性布朗斯特酸催化的重要领域。以最具成本效益的方式制备复杂的手性分子的能力直接取决于可持续合成方法的可用性。在这项工作中探索和开发的新合成方法具有改善对重要化合物（例如多环芳烃和乳酸）的机会，并在化学和制药行业以及整个学术界都有潜在的应用。此外，该项目提供了理想的训练场，以准备化学科学领域的下一代研究人员。来自不同机构的本科生将参加计划中的活动。该项目的一个主要目标是发展反应，通过手性离子对的干预产生对映体富集的产品。将探索新型的BrønstedAcid和氢键供体催化剂，以促进前所未有的对映选择过程，并解决挑战的合成问题。由于大多数手性BrønstedAcid催化剂Studiod sutiod sutiod现在是基于现在熟悉的Binol-phosphate框架，因此在这一领域有真正的创新空间。重点是通过高度反应性氧化出离子和相关物种的中间体进行的反应。正在开发多功能催化剂，目的是在轻度反应条件下实现酶样催化和对映选择性。该奖项反映了NSF的法定使命，并通过使用基金会的知识分子优点和更广泛的审查标准评估来诚实地获得支持。
