In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Timothy D. Lash of the Department of Chemistry at Illinois State University will explore the synthesis, characterization, and reactivity of porphyrin-like macrocycles, including neo-confused porphyrins and other carbaporphyrinoid systems. Specifically, syntheses of heterobenziporphyrins and heteropyriporphyrins will be developed using a "3 + 1" strategy. The chemistry of previously prepared monocarbaporphyrins will also be studied. A strategy for synthesizing carbaporphyrins and carbachlorins from a cyclopentene dialdehyde and a new route to benzocarbaporphyrins from 6-methoxyazulene will be developed. General approaches to the synthesis of a new class of porphyrin isomers known as neo-confused porphyrins will be investigated. In addition to dicarbaporphyrinoids, tri- or tetracarbaporphyrinoid systems will be studied.This work will not only lead to more efficient routes to carbaporphyrinoid systems but will also allow access to new classes of porphyrin analogues. This project is important to improve our basic understanding of fundamental chemistry concepts such as aromaticity. It also has practical applications for the synthesis of fine chemicals, since the target compounds can be used to construct catalysts for chemical synthesis. In addition, the target compounds are important in medicines, as they have potential applications in photodynamic therapy. These projects not only provide an excellent environment for training undergraduates and master level graduate students in the field of organic synthesis, but they also expose them to the multidisciplinary nature of modern scientific research.

在这个由化学部化学合成项目资助的项目中，伊利诺伊州立大学化学系的Timothy D. Lash教授将探索类卟啉大环化合物的合成、表征和反应性，包括新混乱的卟啉和其他碳卟啉系统。 具体而言，将采用“3+1”策略开发异苯并卟啉和异卟啉的合成。 先前制备的单碳卟啉的化学性质也将被研究。 将开发一种从环戊烯二醛合成碳卟啉和卡巴氯林的策略以及从 6-甲氧基薁蓝合成苯并碳卟啉的新路线。 将研究合成一类新的卟啉异构体（称为新混淆卟啉）的一般方法。 除了二碳卟啉类化合物外，还将研究三碳卟啉类化合物或四碳卟啉类化合物系统。这项工作不仅将导致更有效的类碳卟啉系统途径，而且还将允许获得新类别的卟啉类似物。 该项目对于提高我们对芳香性等基本化学概念的基本理解非常重要。 它在精细化学品的合成方面也具有实际应用，因为目标化合物可用于构建化学合成催化剂。 此外，目标化合物在药物中很重要，因为它们在光动力疗法中具有潜在的应用。 这些项目不仅为有机合成领域的本科生和硕士研究生的培养提供了良好的环境，而且让他们接触到现代科学研究的多学科性质。
