Short and sweet: A concise and modular synthesis of radicicol A and related resorcylic acid lactones using fluorous isolation technology and immobilized reagents is reported (see scheme, R^F=C₃H₆C₆F₁₃, TMSE=2-(trimethylsilyl)ethyl). The compounds are found to be potent (low-nanomolar) inhibitors of selected kinases. Despite their irreversible inactivation of kinases, they show good selectivity amongst a panel of 127 kinases.
