Short and efficient synthesis of heterocyclic compounds are highly desirable in synthetic organic chemistry. It is a dream approach to accomplish these syntheses from readily available starting materials in a single step. In this personal account, we discuss our contribution in the synthesis of heterocyclic compounds and beyond from N-sulfonyl-1,2,3-triazoles and α-diazocarbonyl compounds, which are the precursors for α-imino (carbonyl) metal carbenes in the presence of transition metal catalysts. Functionalization of α-imino(carbonyl) metal carbenes has been achieved through in-situ generated metal-stabilized ylides followed by either intramolecular trapping by non-polar bonds, rearrangement, cycloaddition, or 1,3-insertion fashion, which led to the efficient synthesis of various synthetically important intermediates and heterocyclic compounds.

α-重氮羰基化合物及其前体衍生的金属碳烯的催化功能化

在合成有机化学中非常需要杂环化合物的短而有效的合成。在一个步骤中从容易获得的起始材料完成这些合成是一种理想的方法。在这个个人帐户中，我们讨论了我们在从 N-磺酰基-1,2,3-三唑和 α-重氮羰基化合物合成杂环化合物及其他方面的贡献，这些化合物是 α-亚氨基（羰基）金属卡宾的前体过渡金属催化剂的存在。α-亚氨基（羰基）金属卡宾的功能化是通过原位生成的金属稳定叶立德，然后通过非极性键、重排、环加成或 1,3-插入方式进行分子内捕获来实现的，这导致了高效的合成各种重要的合成中间体和杂环化合物。
