Professor Scheidt is developing new methods for the synthesis of heterocyclic compounds utilizing catalytic, multi-component reactions in which a transition metal complex initiates a cascade involving a metallocarbenoid and Lewis base-containing molecules. The reactive intermediate generated will be trapped by a subsequent cycloaddition reaction. Use of chiral ligand-transition metal complexes as catalysts will allow enantiocontrolled heterocyclic synthesis, while intramolecular variants will permit the rapid construction of complex polycyclic products. Professor Scheidt will develop new broad-platform molecular visualization capabilities designed to enhance classroom and Web-based learning, and he will facilitate the transfer of this technology to the high school arena through establishment of a high school teacher outreach program.With this CAREER award, the Organic and Macromolecular Chemistry Program is supporting the teaching and research efforts of Professor Karl A. Scheidt, of the Department of Chemistry at Northwestern University. Professor Scheidt is developing novel methods for the rapid construction of complex organic structures, exploiting the unusual reactivity and versatility of metal complexes. His methods hold promise for general utility in the synthesis of the complex molecular structures often displaying important chemical or biological properties. In order to facilitate student learning about the often confusing three-dimensional structures of organic molecules, Professor Scheidt is developing versatile and accessible methods for visualization of molecular structures. He is introducing these techniques throughout the organic chemistry curriculum and is facilitating their usage in the high school setting through establishment of a high school teacher outreach program.

Scheidt教授正在开发利用催化多组分反应合成杂环化合物的新方法，其中过渡金属配合物引发涉及金属类碳烯和含路易斯碱分子的级联。产生的反应中间体将被随后的环加成反应捕获。使用手性配体-过渡金属配合物作为催化剂将允许对映体控制的杂环合成，而分子内变体将允许快速构建复杂的多环产物。沙伊特教授将开发新的宽平台分子可视化功能，旨在增强课堂和网络学习，他将通过建立高中教师推广计划，促进这项技术向高中领域的转移。凭借这一职业奖，有机和高分子化学项目支持西北大学化学系 Karl A. Scheidt 教授的教学和研究工作。沙伊特教授正在开发快速构建复杂有机结构的新方法，利用金属配合物不寻常的反应性和多功能性。他的方法有望在通常表现出重要化学或生物特性的复杂分子结构的合成中得到普遍应用。为了帮助学生了解经常令人困惑的有机分子三维结构，Scheidt 教授正在开发通用且易于使用的分子结构可视化方法。他在整个有机化学课程中引入这些技术，并通过建立高中教师外展计划促进它们在高中环境中的使用。
