Intramolecular oxazole-olefin Diels-Alder reactions proceed, in the presence of the Lewis acid europium(fodh to provide substituted SH-Ill-benzopyranoI4,3-blpyridines and benzoIh]-1,6 naphthyridines in moderate yields. In the past several years, 5-oxo-5H-[l]-benzopyrano[4,3-blpyridine derivatives 1
A novel, efficient synthesis of a series of functionalized, benzo-annelated decahydrofuro [3,2h][1,6]naphthyridine derivatives 3 has been achieved. The protocol is based on the intramolecular hetero-Diels-Alder (IMHDA) reaction of in situ formed imines derived from an N-prenylated sugar aldehyde 1 a
