developed. The synthesis proceeds stereoselectively in three steps, using 1,3-dipolar cycloaddition of azomethine ylides as a key step. First, a series of 4-arylpyrrolidine-3-carboxylic acids have been prepared from the appropriate cinnamic esters and a non-stabilized azumeihine ylide. The reduction of a nitro group on the aromatic ring was followed by acid-catalyzed intramolecular lactamformation.
A new route to the pyrrolo[3,4-c]quinoline ring system has been developed. The synthesis proceeds stereoselectively in three steps, using 1,3-dipolar cycloaddition of azomethine ylides as a key step.

A modular approach to explore the macrocyclic chemical space around an aminoindoline scaffold is developed. This is achieved by incorporating an amino acid moiety and subsequent stitching technolog ...

The present invention relates to acetal derivatives of bicyclo\x9b2.2.1!hepta-2,5-diene-7-one (norbornadienone) which are capable of releasing carbon monoxide upon irradiation with ultraviolet light, and a method for producing carbon monoxide employing the same.
