title: From simple furans to complex nitrogen-bearing aromatic polycycles by means of a flexible and general reaction sequence initiated by singlet oxygen.
abstract: All-in-one: A new and general one-pot reaction sequence initiated by singlet oxygen that transforms simple furan substrates into complex nitrogen-bearing aromatic polycycles having all the structural features of a number of important natural products (for example, the erythrina alkaloids; see scheme, RB = rose Bengal) is reported. The reaction sequence itself uses mild conditions and has wide functional group tolerance.
