Abstract: Diels-Alder cycloaddition between terpinene and maleic anhydride was studied.Meanwhile isomerization conversion was studied.With excessive amount of maleic anhydride,the percent conversions of isomerization were:15%,38% and:69% at temperature rangs of 65-70℃, 100-105℃ and 135-140℃, respectively.The structure of cycloaddition product was charac-terized by NMR spectra of HMBC.

Key words: Diels-Alder reaction, maleic anhydride, terpinene
