摘要/Abstract
二氧化碳具有价廉易得、储量丰富及无毒等优点，在有机合成反应中是一种理想的C1合成子.近年来，以二氧化碳作为羰基/羧基源，通过环化反应，特别是多组分环化反应构建含羰基杂环化合物，已经取得了重要的研究进展.主要总结了利用含氮、氧亲核原子的试剂与常压条件下二氧化碳的环化反应构建苯并噁嗪、环碳酸酯、内酰胺、2，4-二噁唑啉酮等含羰基杂环结构的工作；其次，也总结了利用含碳亲核原子的试剂与二氧化碳羧基化反应的相关工作.

Carbon dioxide is a readily available, low-cost, abundant, non-toxic C1 source, which can potentially serve as an ideal building block in synthetic chemistry. Recently, much progress, expecially multi-component reactions (MCRs) has been achieved in construction of carbonyl-containing heterocycles through annulation by using carbon dioxide as carbonyl/carboxyl source. Herein, the advances on the annulation reaction of atmospheric CO2 with N-, and O-nucleophiles for the constructioin of various carbonyl-containing heterocycles, including benzoxazin, cyclic carbamates, lactams, oxazolidine-2,4-diones are reviewed. In addition, the carboxylation of C-nucleophiles with CO2 toward carboxylic acids is also summarized.
Key words: carbon dioxide, multicomponent reaction, annulation, carboxylic acid, heterocycle
