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 SmI(2), 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.
描述了一种从13-脱氧巴卡亭III高效合成13-表-7-O-(三乙基甲硅烷基)巴卡亭III的方法。用叔丁基过氧化物氧化13-脱氧-7-O-(三乙基甲硅烷基)巴卡亭III，然后用SmI(2)还原，以良好的总收率得到13-表-7-O-(三乙基甲硅烷基)巴卡亭III。还报道了使用高钌酸四丙铵和N-甲基吗啉N-氧化物从13-表-7-O-(三乙基甲硅烷基)巴卡亭III制备13-氧代-7-O-(三乙基甲硅烷基)巴卡亭III的方法。
