MODIFICATION OF NOVEL ISOXAZOLINES OF FULVENE DERIVATIVES WITH 1,3-DIPOLAR CYCLOADDITION REACTION
In this work, 1,3-Dipolar cycloaddition reactions were studied to synthesize fulvene derivatives containing isoxazoline groups in good yields. 1,3-Dipolar cycloaddition reactions are among the most useful strategies for the preparation of organic ...
