Abstract
1,4-benzoxazine compounds are an important class of heterocyclic compounds. Ever since 1,4-benzoxazine was discovered in 1959, it has attracted chemists due to its unique physiological activities, and their synthesis and application have been studied. However, the traditional synthesis methods of 1,4-benzoxazines have some drawbacks, such as complicated steps, harsh reaction conditions and low yield. Therefore, it is still a significant direction to develop new and efficient synthesis methods. In this paper, the synthesis methods and reaction mechanisms of these compounds are reviewed, and the application prospect of 1,4- benzoxazine and its derivatives as a dominant active structure in the future is discussed.
Keywords: 1, 4-benzoxazines, derivatives, heterocyclic compounds, application, synthesis methods, reaction mechanisms.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
