A synthesis of the unique bisindole framework present in the mushroom-derived alkaloid sciodole has been achieved, validating a biosynthesis proposal that the C–N bisindole bond present in the natural product is forged by amination of an azafulvenium.
A new class of compounds, the thiopyrano[2,3-e]indol-2-ones, bioisosters of the angular furocoumarin angelicin, was synthesized with the aim of obtaining newphotochemotherapeuticagents. In particular 7,8-dimethyl-thiopyranoindolone 6c s showed a remarkable phototoxicity and a great dose UVA dependence reaching IC(50) values at submicromolar level. This latter photoinduced a massive apoptosis and
