C-glycosyl juglone in angucycline synthesis: Total synthesis of galtamycinone, common aglycon of C-glycosyl naphthacenequinone-type angucyclines

A two-step access to C-glycosyl juglones, 16 and 17, useful intermediates toward the angucyclines, either benz[a]anthraquinone- type or naphthacenequinone-type, has been developed based on (1) the O→C-glycoside rearrangement and (2) the regioselective cycloaddition of α-alkoxybenzyne and α-oxyfuran. The first total synthesis of galtamycinone (2), the common aglycon of naphthacenequinone-type angucyclines, has been achieved by utilizing 17 as the key intermediate.

Based on 1H and 13C NMR spectral data and chemical degradation, the structure of capoamycin, a new isotetracenone antibiotic has been determined as shown in Fig. 1.
