Significance
The kinamycins are an interesting class of natural products featuring an unusual diazonaphthoquinone function. Their unique molecular architecture and potent biological activities have made them desirable targets for total synthesis. The group of Porco was the first to disclose a stereoselective synthesis of kinamycin C (X. Lei, J. A. Porco J. Am. Chem. Soc. 2006, 128, 14790) and later the Nicolaou group reported the syntheses of kinamycins C, F and J (K. C. Nicolaou et al. J. Am. Chem. Soc. 2007, 129, 10356). The authors report an expedient total synthesis of kinamycin F, believed to be the active in vivo form of the kinamycins. The key features of the synthesis are a convergent ring formation strategy and a diazo-transfer reaction.
