One-pot, three-component synthesis of nitrogen-containing polycyclic heterocycles bearing two nitrogen atoms such as quinoxaline, quinazoline, and phenazine derivatives by the coupling of appropriate vicinal alkynylheteroaryl carbonyl derivatives with Fischer carbene complexes and dienophiles has been investigated. This involves the generation of furo[3,4-b]pyrazines, furo[3,4-d]pyrimidines, and furo[3
通过适当的邻位炔基杂芳基羰基衍生物与费歇尔卡宾配合物和二亲体的偶联,研究了一锅三组分合成含两个氮原子的含氮多环杂环化合物,如喹喔啉,喹唑啉和吩嗪衍生物。这涉及呋喃[3,4- b ]吡嗪,呋喃[3,4- d ]嘧啶和呋喃[3,4- b ]喹喔啉的瞬时中间体的生成,它们被合适的Diels-Alder二烯亲和物捕获在分子间或分子内方式。 氮杂异苯并呋喃-喹喔啉-喹唑啉-吩嗪-Diels-Alder反应-卡宾络合物
