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(R) 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 hydrolysis provided the taxamycins 21.
