carbene complexes and dienophiles leading to the synthesis of phenanthridine ring system has been investigated. This reaction involves the generation of furo[3,4-c]isoquinolines as transient intermediates, which undergo [4+2] cycloaddition with a dienophile in an inter/intramolecular fashion. In fact, this is the first report of the work on furo[3,4-c]isoquinoline intermediates.
一锅三组分的3-炔基-4-异喹啉羰基衍生物与费歇尔卡宾配合物和亲二烯物的耦合导致了菲啶环系统的合成。该反应涉及呋喃[3,4-c]异喹啉的生成,作为过渡中间体,与亲二烯体以分子间/分子内方式进行[4 + 2]环加成。实际上,这是呋喃[3,4-c]异喹啉中间体研究的第一份报告。
