The reaction of 2(1H)-pyrazinones 1 and 1,2,4-triazoline-3,5-diones 3 was investigated by comparing that of 1 with singlet oxygen. 2(1H)-Pyrazinones 1 reacted in Diels-Alder fashion with 1,2,4-triazoline-3,5-diones 3 to afford [4+2]-adducts 4–17 in high yields.
通过比较1与单线态氧的反应,研究了2(1 H)-吡嗪酮1与1,2,4-三唑啉-3,5-二酮3的反应。2(1 H)-吡嗪酮1以Diels-Alder的方式与1,2,4-三唑啉-3,5-二酮3反应,以高收率提供[4 + 2]加合物4-17。
