摘　　要：环加成反应、环合反应、电环化反应与环化反应都是合成有机环状化合物的成环反应,它们描述的反应类型完全不同。但是,它们却经常被误用或者混用。阐述了这4类反应的区别,希望能够从教学上明确这4类反应,从源头为将来的有机化学工作者建立起准确的概念。Cycloadditions,annulations,electrocyclic reactions,and cyclizations are organic reactions for construction of cyclic organic compounds.They describe different types of organic reactions completely.However,they have been misused and applied randomly sometimes.This article expounds the different characteristics of these four types of organic reactions,hoping to teach them accurately in university course and to establish the exact concepts and definations for future workers on organic chemistry at their beginning.

关 键 词：环加成反应 环合反应 电环化反应 环化反应 区别
