杂环化学

理论课，3学分，3学时/每周。先修课：化学远离A（CH101A）。本课程主要以芳香杂环为主，但也包括一个关于非芳香杂环的简短讲解。我们讨论了最重要的芳香杂环的特征反应性以及其从非杂环的前体合成环的主要途径。本课程的杂环化学主要包括吡啶、哒嗪、嘧啶、吡嗪、喹啉、异喹啉、吡喃和苯并吡喃阳离子、吡咯、吲哚、噻吩、呋喃、咪唑、恶唑、噻唑、吡唑、异恶唑、异噻唑、嘌呤、杂环与超过两个杂原子的杂环化合物（例如氮杂四唑和三嗪）和位于一个环的杂原子的杂环化合物。 Lecture, 3 credits, 3 hours per week. Prerequisites: CH101A. This course is mainly concerned with aromatic heterocycles though we also include a short discussion of non-aromatic heterocycles. We deal with the characteristic reactivities of the most important heteroaromatic systems and the principal routes for their ring synthesis from non-heterocyclic precursors. Thus the chemistry of pyridines, pyridazines, pyrimidines, pyrazines, quinolines, isoquinolines, pyrylium and benzopyrylium cations, pyrroles, indoles, thiophenes, furans, imidazoles, oxazoles, thiazoles, pyrazoles, isoxazoles, isothiazoles, purines, heterocycles with more than two heteroatoms in the ring (for example triazoles and triazines) and heterocycles in which a heteroatom is located at a ring junction (for example pyrrolizines and indolizines) is covered.
