with Fischer carbene complexes and dienophiles leading to the synthesis of quinoxaline and phenazine ring systems has been investigated. This involves the generation of furo[3,4-b]pyrazine and furo[3,4-b]quinoxaline as transient intermediates, which were trapped with Diels-Alder dienophiles. This is the first report on furo[3,4-b]pyrazine intermediates.
已经研究了邻炔基杂芳基羰基衍生物与 Fischer 卡宾配合物和亲二烯体的一锅三组分偶联,导致喹喔啉和吩嗪环系统的合成。这涉及生成呋喃 [3,4-b] 吡嗪和呋喃 [3,4-b] 喹喔啉作为瞬态中间体,它们被 Diels-Alder 亲二烯体捕获。这是关于呋喃[3,4-b] 吡嗪中间体的第一份报告。
