| Abstract: | The title compounds 5 can be easily obtained by two alternative procedures: 1,3-dipolar cycloaddition to benzamidocinnamates 3 prepared by methanolysis of the corresponding oxazolones 1 or methanolysis of the spirooxazolones 4 synthesized by 1,3-dipolar cycloaddition to oxazolones 1 . Both reaction sequences show the same stereo and regioselectivity. |
