A mild, efficient, and highly selective method for the synthesis of pyranoquinoline and furoquinoline derivatives via a three-component reaction of aromatic aldehyde, naphthalen-2-amine or anthracen-2-amine and 2,3-dihydrofuran, or 3,4-dihydro-2H-pyran catalyzed by iodine is described. It should be noted that exo-isomer was obtained with high selectivity in good yields, which was confirmed by X-ray
通过芳族醛,萘-2-胺或蒽-2-胺与2,3-二氢呋喃或3,4-的三组分反应合成吡喃喹啉和呋喃喹啉衍生物的温和,高效且高度选择性的方法描述了碘催化的二氢-2H-吡喃。应当指出,通过X-射线衍射分析证实了以高收率以高选择性获得外型-异构体。当使用链正丁基乙烯基醚作为反应物时,高收率地分离出了3-芳基苯并(石脑油)[f]喹啉,但是丁氧基的意外损失。
