New Boron-Element Addition Reactions

具有先进技术特性的现代材料，以及治疗人类疾病的新型药物化合物，都是通过将相对较小的构建块组合成更大、更复杂的结构而构建的。这些组合受到可用的小型构建块类型的限制。因此，构建新的先进材料和产生新的药物的能力反过来又受到可用的小型构建块的种类的限制。在这个项目中，Blum博士正在开发新的流程来创建新的构建模块。这些新的构建模块被设计成组合，从而构建更大、更复杂的材料和具有改进性能的治疗剂。新工艺涉及可持续的合成方法，通过使用地球上丰富的添加剂，或者在某些情况下，通过不添加添加剂。Blum博士是一个教师培训项目的主任，该项目为加州大学欧文分校的现有高级学生提供教学培训、指导和技能，以教授下一代大学生。该教师培训计划侧重于化学科学有效课堂教学的培训，包括在研究实验室中发展的科学概念的教学。在美国国家科学基金会化学部化学合成项目的资助下，加州大学欧文分校的Blum博士正在开发新的硼杂原子加成反应。这些反应的产物是硼化的构建块，对药物发现和材料合成有用。这些反应发展了以前未知的硼氧sigma键到碳碳pi键的加成化学，并将这种加成化学扩展到硼氮加成反应。硼/氧、硼/氮和硼/硫等价物的机械不同的形式加成反应也正在开发中，以获得类似的产品类别，并比较了两种方法（直接和形式）的效率。研究包括在无催化剂条件下发展这些反应，这提供了一种比传统贵金属催化硼化策略更可持续的方法。Blum博士是一个教师培训项目的负责人，该项目为加州大学欧文分校的在读博士生提供教学培训、指导和技能，以教授下一代大学生。该教师培训计划侧重于化学科学有效课堂教学的培训，包括在研究实验室中发展的科学概念的教学。

Modern materials with technologically advanced properties, and new pharmaceutical compounds to treat human disease, are all constructed through the combination of relatively small building blocks into larger and more complex structures. These combinations are limited by the types of small building blocks available. Thus, the ability to construct new advanced materials and to generate new pharmaceuticals is, in turn, limited by the variety of small building blocks available. In this project, Dr. Blum is developing new processes to create classes of new building blocks. These new building blocks are designed to be combined and thus to construct larger, complex materials and therapeutic agents with improved properties. The new processes involve sustainable approaches to synthesis by using Earth-abundant additives or, in some cases, by being additive-free. Dr. Blum is the director of a teacher-training program that provides current advanced students at the University of California, Irvine, with pedagogical training, mentorship, and skills for teaching the next generation of college students. This teacher-training program focuses on training in effective classroom instruction in the chemical sciences, including the instruction of scientific concepts developed in the research laboratory. With funding from the Chemical Synthesis Program in the Chemistry Division of the National Science foundation, Dr. Blum of the University of California, Irvine, is developing new boron-heteroatom addition reactions. The products from these reactions are borylated building blocks that are useful for drug discovery and materials synthesis. These reactions develop the previously unknown addition chemistry of boron-oxygen sigma bonds to carbon-carbon pi bonds, and extend this addition chemistry to boron-nitrogen addition reactions. Mechanistically distinct formal addition reactions of the equivalents of boron/oxygen, boron/nitrogen, and boron/sulfur are also being developed to access similar product classes and the two methods (direct and formal) are compared for efficiency. Studies include the development of these reactions with catalyst-free conditions, which provide a more sustainable approach than alternative traditional precious-metal-catalyzed borylation strategies.
