Cross-coupling approach towards dynemicin analogs without the nitrogen

Article abstract of DOI:10.1016/S0040-4020(97)00616-9

Utilizing a cross-coupling reaction between the arylstannane 5 and the iodoenone 7, the arylcyclohexenone 8 was prepared. This compound was then transformed into the enediyne aldehydes 16a,b. Treatment of 16a with cat, amounts of TBAF gave rise to the macrocyclic dynemicin analog 17a. This was converted to the phenolic enediyne 18.
