method for constructing 1,4-pyrazoles from arylglycines was developed using the copper-catalyzed sydnone–alkyne cycloaddition reaction. The procedure offers a straightforward and general route to the pyrazole heterocycle through a three-step one-pot procedure.
利用铜催化的sydnone-炔烃环加成反应,开发了一种从芳基甘氨酸构建1,4-吡唑的可靠方法。该程序通过三步一锅法为吡唑杂环提供了一条简单而通用的途径。
