Using a versatile synthesis with 13CH3PPh3I and CH313CO2Et as 13C sources, the first examples of nine-membered chromophores which have been differentially labelled with 13C in their carbocyclic enediyne cores are described.

Efficient construction of the bicyclo[7.3.0]dodecenediyne cores of chromophore of C-1027 (1) and neocarzinostatin (2) was obtained via the C-C bond formation at C5-C6 using the LiN(SiMe3)2/CeCl3-mediated acetylide-aldehyde condensation reaction.
