title: Synthesis of 13C-labelled, bicyclic mimetics of natural enediynes.
abstract: Using a versatile synthesis with 13CH3PPh3I and CH(3)13CO2Et as 13C sources, the first examples of nine-membered chromophores which have been differentially labelled with 13C in their carbocyclic enediyne cores are described.
