An approach to the pyrroloquinoline core of martinelline and martinellic acid

An expedient method for the assembly of the pyrroloquinoline skeleton found in the martinelline alkaloids using a [3+2] cycloaddition of an azomethine ylide and an alkene has been developed.

Tandem Long Distance Chain-Walking/Cyclization via RuH2(CO)(PPh3)3/Br?nsted Acid Catalysis: Entry to Aromatic Oxazaheterocycles

A novel route to 1,3-oxazaheterocycles based on cooperative Ru-H/Br?nsted acid catalysis is reported. The use of the commercially available RuH2(CO)(PPh3)3 complex allows for an efficient long distance chain-walking process while the Br?nsted acid is responsible for generation of an electrophilic iminium ion which is trapped intramolecularly by an alcohol moiety. The alcohol, besides its nucleophilic function, also plays an important role in the stabilization of the Ru catalyst. (Chemical Equation Presented).

An intramolecular azomethine ylide-alkene cycloaddition approach to pyrrolo[3,2-c]quinolines-synthesis of a C2-truncated martinelline model

The hexahydropyrrolo[3,2-c]quinoline core found in the Martinella alkaloids was constructed through an intramolecular [3+2] azomethine ylide-alkene cycloaddition. Some chemical manipulations of the tricycle are reported.
