Polycyclic indolic compounds containing the [6,5,6,5,6] ring system were prepared via an intramolecular furan Diels–Alder reaction of α,β-unsaturated amides generated by the N-acylation of 1-(2-furyl)-β-tetrahydrocarbolines. This chemistry can provide access to D(14)-noryohimban derivatives by exploiting the functionality on the C,D,E ring system of the corresponding cycloadducts.
含有[6,5,6,5,6]环系统的多环吲哚化合物是通过分子内呋喃Diels-Alder反应制备的,该反应由1-(2-呋喃基)-的N-酰化反应生成的α,β-不饱和酰胺β-四氢咔啉。通过利用相应环加合物的C,D,E环系统上的官能团,该化学物质可提供对D(14)-去核育亨班衍生物的访问。
