项目摘要

The Chemical Catalysis Program of the Chemistry Division supports the project by Professor Steven E. Wheeler. Professor Wheeler is a faculty member in the Center for Computational Quantum Chemistry, Department of Chemistry at the University of Georgia. He is developing a free, open-source computational toolkit (AARON) to facilitate the design of transition-metal free asymmetric catalysts. This toolkit is being implemented to help develop new catalysts with applications in the synthesis of complex natural products and pharmaceuticals. This project will make it easier for non-specialists to use computational chemistry to design and evaluate new organocatalysts. The primary goal of this project is to provide computational tools that reduce the time and materials required to design new catalysts, thereby streamlining the catalyst design process. The project combines ideas from computational quantum chemistry, software development, data analytics, and organic synthesis, and provides graduate and undergraduate students with diverse training in highly transferrable skills. The project also supports a workshop on computational organic chemistry that is held in conjunction with an annual undergraduate computational chemistry conference organized by the MERCURY consortium.The development of new asymmetric organocatalysts typically depends on the experimental screening of a library of potential catalysts to identify the best catalysts for a single substrate. The substrate scope of this catalyst is then tested. The AARON program provides an alternative path for the development of organocatalysts with broad substrate scope by enabling the automated computational screening of virtual libraries of catalysts applied to multiple substrates simultaneously. In this way, the synthesis and testing of new catalysts can be prioritized based on predicted stereoselectivities and catalytic activities across a range of substrates. AARON is designed to identify novel bifunctional hydrogen bonding catalysts and chiral phosphoric acids for several reactions and to unravel the origin of stereoselectivity in ion-pairing catalysis. The development of an accompanying graphical interface for AARON enable its widespread use among organic chemists, while an online public database provides access to transition state structures, energies, and stereoselectivities, facilitating the application of modern data analysis tools to these rich datasets. Educational activities include the training of undergraduate and graduate students in computer programming, advanced electronic structure theory, and physical organic chemistry. Outreach activities include the development of a computational organic chemistry workshop for undergraduates, and the training of students in modern data analytics through the Georgia Informatics Institutes (GII).

化学系的化学催化项目支持Steven E.惠勒。惠勒教授是格鲁吉亚大学化学系计算量子化学中心的教员。他正在开发一个免费的开源计算工具包（AARON），以促进过渡金属自由不对称催化剂的设计。该工具包正在实施，以帮助开发新的催化剂，用于合成复杂的天然产物和药物。该项目将使非专业人员更容易使用计算化学来设计和评估新的有机催化剂。该项目的主要目标是提供计算工具，减少设计新催化剂所需的时间和材料，从而简化催化剂设计过程。该项目结合了计算量子化学，软件开发，数据分析和有机合成的想法，并为研究生和本科生提供了高度可转移技能的多样化培训。该项目还支持一个计算有机化学研讨会，该研讨会与MERCURY财团组织的年度本科生计算化学会议一起举行。新的不对称有机催化剂的开发通常取决于对潜在催化剂库的实验筛选，以确定单一底物的最佳催化剂。然后测试该催化剂的底物范围。AARON计划通过实现同时应用于多种底物的催化剂虚拟库的自动计算筛选，为开发具有广泛底物范围的有机催化剂提供了另一种途径。以这种方式，新催化剂的合成和测试可以基于预测的立体选择性和在一系列底物上的催化活性来优先考虑。 AARON的目的是确定新的双功能氢键催化剂和手性磷酸的几个反应，并解开离子配对催化的立体选择性的起源。AARON附带的图形界面的开发使其在有机化学家中得到广泛使用，而在线公共数据库提供了对过渡态结构，能量和立体选择性的访问，促进了现代数据分析工具对这些丰富数据集的应用。教育活动包括计算机编程，高级电子结构理论和物理有机化学的本科生和研究生的培训。外联活动包括为本科生举办计算有机化学讲习班，以及通过格鲁吉亚信息学研究所（GII）对学生进行现代数据分析培训。
