The synthesis of the bicyclic enediyne compounds 14–18 is described. The bicyclo [7.3. 1] trideca-4, 9-dien-2, 6-diynes (21) are calicheamicin-taxoid mimics, that possess the Taxotere® side chain and an enediyne core. Cyclization of the iodo-aldehyde 13 [CrCl2 (THF) 2] afforded the bicyclic alcohol 14 as a single diastereomer (76%) and allylic oxidation (SeO2) followed by reaction with the oxazolidine intermediate 19, resolution and ...
