An efficient synthesis of 13-epi-7-O-(triethylsilyl)baccatin III from 13-deoxybaccatin III is described. Oxidation of 13-deoxy-7-O-(triethylsilyl)baccatin III with tert-butyl peroxide, followed by reduction with SmI2, produced 13-epi-7-O-(triethylsilyl)baccatin III in good overall yield. The preparation of 13-oxo-7-O-(triethylsilyl)baccatin III from 13-epi-7-O-(triethylsilyl)baccatin III using tetrapropylammonium perruthenate and N-methylmorpholine N-oxide is also reported.
