项目摘要

This award to Ohio State University by the Chemistry Division is part of the Nanoscale Exploratory Research in the Nanoscale Science and Engineering program. Under this project, Jonathan Parquette will develop novel enantioselective catalysts based on the active transition metals, such as ruthenium and copper, incorporated in chiral dendrimers. Monodendrons up to three generations will be prepared using aminopyridine dicarboxamide as the branching units, and chiral nonracemic anthranilamide as the terminal units. Dendrimers with transition metals will be evaluated for enhanced catalytic Diels-Alder and aldol condensation reactions. In addition, the research program will provide education and training opportunities in material chemistry to graduate and undergraduate students.Under the award, novel enantioselective catalysts based on the active transition metals in chiral dendrimers will be studied. Dendrimers, with up to three generations, will be synthesized and their conformationally based chiral changes in different solvents will be evaluated using circular dichroism. In addition, different metals selectively placed at the periphery of dendrimers will be evaluated for enhanced catalytic activities for the organic synthesis of chiral materials. The research program will provide education and training opportunities in materials chemistry to graduate and undergraduate students.

该奖项由俄亥俄州立大学化学系授予，是纳米科学与工程项目纳米探索性研究的一部分。在这个项目中，Jonathan Parquette将开发基于活性过渡金属（如钌和铜）的新型对映选择性催化剂，将其结合在手性树状大分子中。以氨基吡啶二甲酰胺为分支单元，手性非外消旋氨基甲酰胺为末端单元，制备三代单枝植物。具有过渡金属的树状大分子将被评价为增强催化diols - alder和醛醇缩合反应。此外，该研究计划将为研究生和本科生提供材料化学方面的教育和培训机会。根据该奖项，将研究基于手性树状大分子中活性过渡金属的新型对映选择性催化剂。树状大分子，多达三代，将合成和他们的构象为基础的手性变化在不同的溶剂将评估使用圆二色性。此外，不同的金属选择性地放置在树状大分子的外围将评估其对手性材料有机合成的增强催化活性。该研究项目将为研究生和本科生提供材料化学方面的教育和培训机会。
