介绍了利用4族金属环组装碳-碳和碳杂原子不饱和键制备杂环化合物的方法。制备方法分为四类：1)乙炔和/或烯烃与杂亲电试剂偶联形成金属环的反应；2)两个碳-碳不饱和键与一个碳-杂原子不饱和键的偶联；3)一个碳-碳不饱和键与两个碳-杂原子不饱和键的偶联；4)功能化乙炔和烯的分子内杂金属化。
Preparation of heterocyclic compounds by the assembly of carbon-carbon and carbon-heteroatom unsaturated bonds via group 4 metallacycles was described. The preparative methods are classified into four categories : 1) reaction of metallacycles formed by the coupling of acetylenes and/or olefins with hetero-electrophiles, 2) coupling of two carbon-carbon unsaturated bonds and one carbon-heteroatom unsaturated bond, 3) coupling of one carbon-carbon unsaturated bond and two carbon-heteroatom unsaturated bonds, and 4) intramolecular hetero-metallation of functionalized acetylenes and allenes.
